Stash some notes and tests on update checking

We ideally want to trigger configure updates, patching repeats, etc. when git repository updates are pulled down, but because most of our builds make src copies and apply patches an update into the src git tree doesn't automatically trigger rebuilding. Investigating whether a custom update step can be made to do the steps for us automatically. The addition of patching makes what needs to happen for this a bit involved - what's being committed here is just the beginnings of thinking about how to do what's needed, and is not functional.

-
-Imported Targets
-^^^^^^^^^^^^^^^^
-
-This module provides the following imported targets, when found:
-
-``ZLIB::ZLIB``
-  Compatibility/default target that encapsulates the selected zlib usage
-  requirements.  Selection follows ``ZLIB_USE_STATIC_LIBS`` when set.
-
-``ZLIB::ZLIB_SHARED``
-  Shared zlib target, when a shared zlib library can be identified.
-
-``ZLIB::ZLIB_STATIC``
-  Static zlib target, when a static zlib library can be identified.
-
-``ZLIB::ZLIBSTATIC``
-  Alias to ``ZLIB::ZLIB_STATIC`` when the static target is available.  This
-  matches the target name used by zlib's own CMake package.
-
-Result Variables
-^^^^^^^^^^^^^^^^
-
-``ZLIB_FOUND``
-  Boolean indicating whether zlib was found.
-
-``ZLIB_VERSION``
-  The version of zlib found.
-
-``ZLIB_INCLUDE_DIRS``
-  Include directories containing ``zlib.h`` and other headers needed to use
-  zlib.
-
-``ZLIB_LIBRARIES``
-  List of libraries needed to link to the default/selected zlib.
-
-``ZLIB_SHARED_FOUND``
-  Boolean indicating whether a shared zlib library was found.
-
-``ZLIB_STATIC_FOUND``
-  Boolean indicating whether a static zlib library was found.
-
-``ZLIB_SHARED_LIBRARIES``
-  Shared zlib library or debug/optimized library list, when found.
-
-``ZLIB_STATIC_LIBRARIES``
-  Static zlib library or debug/optimized library list, when found.
-
-Hints
-^^^^^
-
-``ZLIB_ROOT``
-  A user may set this variable to a zlib installation root.
-
-``ENV{ZLIB_ROOT}``
-  Environment-variable form of ``ZLIB_ROOT``.
-
-``ZLIB_USE_STATIC_LIBS``
-  Set to ``ON`` before calling ``find_package(ZLIB)`` to prefer static
-  libraries for the compatibility/default ``ZLIB::ZLIB`` target.
-
-``ZLIB_NAMES`` and ``ZLIB_NAMES_DEBUG``
-  Optional project override for the default selected-library search names.
-
-``ZLIB_SHARED_NAMES`` and ``ZLIB_SHARED_NAMES_DEBUG``
-  Optional project override for shared-library search names.
-
-``ZLIB_STATIC_NAMES`` and ``ZLIB_STATIC_NAMES_DEBUG``
-  Optional project override for static-library search names.
-
-The default name lists include BRL-CAD's custom ``z_brl`` name.

-This file is a package map for `bext`.  It shows which `USE_*` groups can bring
-each project into scope and whether its outputs land in `install/` or
-`noinstall/`.
-
-A package listed here may still use a system installation instead of building a
-local copy unless `ENABLE_ALL=ON` or `ENABLE_<pkg>=ON` is used.
-
-For some BRL-CAD-related packages, `BRLCAD_COMPONENTS` can narrow the final
-selection further.
-
-# Output types
-
-* `install` - bundled output intended for downstream use

-# Notes
-
-* `install/` versus `noinstall/` is about downstream use, not importance.
-  Several `noinstall` entries are essential build helpers.
-* `ENABLE_ALL=ON` does not add `USE_APPLESEED` or `USE_OSPRAY` by itself.
-  Those groups still need to be enabled explicitly.
-* A few source trees, such as `patchelf`, are present in the repository but are
-  not currently added by the top-level build.
-* Run the `update_dependency_docs` target after changing project groups,
-  dependency edges, output locations, or submodule sources.  CI runs
-  `check_dependency_metadata` to detect drift, unknown edges, cycles, missing
-  source pins, and missing bundled-output license installation.
-* The `sbom` target writes an SPDX 2.3 JSON inventory to `bext.spdx.json` in
-  the build directory.  `supply_chain_check` validates metadata and produces
-  the SBOM together.
-
-# Adding a dependency
-
-For maintainers, the high-level workflow for adding a new dependency to `bext`
-is:
-
-1. Decide whether the dependency belongs in `bext` at all.
-Only add repositories that are expected to support live BRL-CAD or related
-build features.  Exploratory work that may be discarded should stay in a branch
-until the dependency choice is settled.
-
-2. Prepare the BRL-CAD-hosted source repository first.
-`bext` generally points at BRL-CAD-managed copies of upstream sources rather
-than upstream repositories directly.  Before wiring anything into `bext`, make
-sure the BRL-CAD copy has the intended `RELEASE` content, submodules handled as
-needed, and license files available for installation.
-
-3. Choose the `USE_*` group or groups that should bring the dependency into
-scope.
-This controls when the dependency is considered at all.  If none of the
-existing groups fit, add a new one only if it represents a real build profile
-that users can reason about.
-
-4. Add the new top-level directory and git submodule.
-The directory should usually contain:
-* the upstream source as a git submodule
-* a managing `CMakeLists.txt`
-* a `<name>.deps` file listing other `bext` projects it depends on
-* any patch files or helper resources needed by the build
-
-After `git submodule add`, update `.gitmodules` to include `ignore = dirty` for
-the new entry, consistent with the existing submodules.
-
-5. Add the build logic.
-Follow the patterns used by nearby dependencies:
-* use `git_submodule_init(...)`
-* use `RegisterDeps(...)`
-* decide whether the outputs belong in `install` or `noinstall`
-* copy license files into `${DOC_LICENSE_DIR}`
-* use `bext_enable(...)`, `cad_enable(...)`, or custom logic as needed to
-  respect system detection and BRL-CAD component selection
-
-6. Register the dependency in the top-level build.
-Add `add_project(...)` to the top-level `CMakeLists.txt` in dependency order so
-that any prerequisites appear earlier in the file.
-
-7. Update the docs.
-At minimum:
-* add the project to this file
-* update `INSTALL.md` if the new dependency adds system prerequisites
-* update `NOTES.md` if the dependency needs special submodule or maintainer
-  handling
-
-8. Test the intended selection behavior and build flow.
-Check at least:
-* the default configure path for the relevant `USE_*` groups
-* `-DENABLE_ALL=ON`
-* any new or changed prerequisite detection
-* downstream use if the outputs are intended for BRL-CAD bundling
-
-9. Only after the dependency is working, commit the new submodule reference and
-the `bext` integration together.
-That keeps the repository history aligned with a working configuration rather
-than a partial experiment.
-
-For lower-level git and submodule procedures, see [NOTES.md](NOTES.md).

-# bext - Installation Notes
+# bext - Installation

-This file covers machine setup and source checkout details.  For the main build
-flow and option behavior, see [README.md](README.md).
-
-# Base requirements
-
-All builds need:
-
-* Git
-* CMake 3.19 or newer
-* A modern C compiler
-* A modern C++ compiler
-
-Additional requirements depend on the enabled stacks:
-
-* `USE_APPLESEED` and `USE_OSPRAY` will use a system `flex` and
-  `bison` if they are already installed.  If they are not and `bext`
-  needs to build them locally on non-Windows platforms, a working
-  Autotools stack is also needed.
-* `USE_QT`, `USE_APPLESEED`, or `USE_OSPRAY` need Python 3 available
-  to the build.
-* `USE_OSPRAY` needs `m4`.
-
-# Source checkout options
-
-Default clone:
-
-```sh
-git clone https://github.com/BRL-CAD/bext
-```
-
-This is usually the best starting point.  `bext` will populate submodules on
-demand during configure.
-
-Recursive clone:
-
-```sh
-git clone --recursive https://github.com/BRL-CAD/bext
-```
-
-Use this if you want all submodule content fetched up front, or if you expect
-to configure and build without network access later.
-
-Shallow clone options:
-
-* `cmake ../bext -DGIT_SHALLOW_CLONE=ON ...`
-* `git clone --recursive --depth=1 https://github.com/BRL-CAD/bext`
-
-Shallow clones are fine for compile-only use, but they are not recommended for
-development or for submodule update work.
-
-# Alternate repositories and offline mirrors
-
-`BEXT_REPOSITORY_ROOT` selects the directory containing the dependency
-repositories.  It defaults to `https://github.com/BRL-CAD`.  For another host,
-specify the URL of the equivalent repository directory:
-
-```sh
-cmake --preset auto -DBEXT_REPOSITORY_ROOT=https://git.example.org/brlcad
-```
-
-For offline use, the directory can contain bare Git mirrors such as
-`bext.git`, `astyle.git`, and `libpng.git`, as produced by BRL-CAD's
-`sh/mirror_repos.sh`.  Clone bext first, then let CMake populate the required
-submodules:
-
-```sh
-git clone /path/to/mirror/BRL-CAD/bext.git
-cd bext
-cmake --preset auto -DBEXT_REPOSITORY_ROOT=/path/to/mirror/BRL-CAD
-```
-
-The root points directly to the repositories; CMake does not append `BRL-CAD`.
-Local paths and `file://` URLs are supported, as are remote Git URLs including
-`ssh://` URLs.  Relative local paths are resolved against the bext source
-directory.  Quote the `-D` argument if the path contains spaces.  The setting
-is saved in the configure cache.
-
-The optional bootstrap script accepts the same setting:
-
-```sh
-cmake -DPROFILE=auto -DBEXT_REPOSITORY_ROOT=/path/to/mirror/BRL-CAD \
-  -P CMake/BextBootstrap.cmake
-```
-
-Bootstrap runs separately from configure, so pass the setting to both commands
-if you use both workflows.  `LIST_ONLY=ON` previews bootstrap selection without
-fetching.
-
-CMake redirects `https://github.com/BRL-CAD/` URLs using command-scoped Git
-configuration, including recursive submodule operations.  Local roots enable
-file transport and forbid network transport for those Git operations.  They
-also disable shallow-clone recommendations, even with `GIT_SHALLOW_CLONE=ON`,
-so full mirrors can supply older pinned commits.  The mirrors must contain all
-required commits.  Recursive submodules outside that URL prefix need their
-own Git URL mappings and local mirrors; otherwise initialization fails.
-
-The override does not change `.gitmodules` or install persistent Git rewrite
-settings.  To return CMake-driven updates to GitHub, set
-`-DBEXT_REPOSITORY_ROOT=https://github.com/BRL-CAD`.  Direct Git commands use
-their normal configuration.  This setting controls submodule fetching, not
-network access by dependency build scripts.
-
-# Path and directory caveats
-
-* Avoid symlinked source or build directory paths.  `bext` warns about these
-  because they can cause downstream install and rpath problems.
-* On non-Windows platforms, bundled Tcl/Tk builds do not support spaces in the
-  source or build directory path.
+For building all of the projects present in this repository, you will need Git, CMake, a modern C/C++ compiler and some support libraries installed on your operating system.  If you want flex and bison you'll also need a working Autotools stack on non-Windows platforms.

 # Ubuntu Linux

-Base packages:
-
-```sh
+Basic tools needed for all configurations:
+```
 sudo apt install git cmake gcc g++
 ```

-For Tcl/Tk builds:
-
-```sh
+For Tk you'll need basic X11 libraries:
+```
 sudo apt install libfontconfig1-dev libfreetype6-dev xserver-xorg-dev libx11-dev libxi-dev libxext-dev
 ```

-For Qt, Appleseed, and OSPRay:
-
-```sh
+For Qt, Appleseed and OSPRay you'll need Python
+```
 sudo apt install libpython3-dev
 ```

-For Qt on X11 systems, install the XCB development packages:
-
-```sh
+For Qt you'll also need (in addition to the above) the XCB packages (see https://doc.qt.io/qt-6/linux-requirements.html)
+```
 sudo apt install libx11-xcb-dev libxfixes-dev libxrender-dev libxcb1-dev libxcb-cursor-dev libxcb-glx0-dev libxcb-keysyms1-dev libxcb-image0-dev libxcb-shm0-dev libxcb-icccm4-dev libxcb-sync-dev libxcb-xfixes0-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-render-util0-dev libxcb-util-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev
 ```

-For OSPRay:
-
-```sh
+For OSPRay you'll need m4, and for the ISPC compiler used by OSPRay you'll need the gcc multilib packages:
+```
 sudo apt install m4 gcc-multilib g++-multilib
 ```

-If you want to rely on system `flex` and `bison`:
-
-```sh
+If you don't want to build flex and bison for the OSPRay/Appleseed stacks you can also install those:
+```
 sudo apt install flex bison
 ```

-If `bext` may need to build `flex` and `bison` locally:
-
-```sh
-sudo apt install autotools-dev autoconf
+If you do want to build them, install the Autotools stack:
+```
+sudo apt-get install autotools-dev autoconf
 ```

 # Windows

-If you enable Qt, Appleseed, or OSPRay, make sure Python 3 is installed and
-available in the build environment.
+Windows will need some variety of Python installed for Qt/Appleseed/OSPRay.

-Keep the source and build directories close to the drive root when possible.
-Some Windows build tools still have path length limits, even though bext enables
-Git's long path handling when it checks out submodules.
+# OSX

-# macOS
+XCode
+
+What else? - TODO

-Assuming XCode is installed, good to go.

 When using submodules, there are some fairly non-intuitive aspects of managing them that need to be taken into consideration:

-# Checkout out particular versions of bext
-
-Because bext makes extensive use of git submodules, operations that in the BRL-CAD repository can normally be achieved with basic git commands may need additional options in bext to achieve expected results.  A common example is switching a clone of bext to a specific revision.  If you have (say) a checkout of main branch but wish to obtain bext's contents from the rel-7-40-2 branch, one might intuitively think a checkout would work.  However, doing that checkout, we see:
-
-```

-# bext - External Dependencies for BRL-CAD
+# bext - External Dependencies Management

-`bext` builds third-party libraries and helper tools used by
-[BRL-CAD](https://github.com/BRL-CAD/brlcad).  By default it prefers suitable
-system packages and builds local copies only when they are needed.
+This repository manages the building of dependencies used by large scale computer graphics projects, with a primary focus on the [BRL-CAD](https://github.com/BRL-CAD/brlcad) computer aided design system.

 # Quick start

-Clone the repository, configure with the official `auto` preset, and build:
-
+* Clone this repository
 ```sh
 git clone https://github.com/BRL-CAD/bext
-cd bext
-cmake --preset auto
-cmake --build build/auto --config Release --parallel 8
 ```
-
-Submodules are populated on demand during configure.  For checkout and
-platform setup details, see [INSTALL.md](INSTALL.md).
-
-The preset workflow relies on CMake's newer preset support.  If you are using
-CMake 3.19 or 3.20, use the raw configure equivalents below.
-
-# Optional bootstrap
-
-If you want to fetch a given profile's source submodules up front
-instead of letting configure fetch them on demand:
-
+(This should be fast - by default most of the downloading happens during the configure process.)
+* Make a build directory
 ```sh
-cmake -DPROFILE=auto -P CMake/BextBootstrap.cmake
-cmake --preset auto
+mkdir bext_build && cd bext_build
 ```
-
-Use `LIST_ONLY=ON` to preview the selected submodules without fetching them,
-and `GIT_SHALLOW_CLONE=ON` to specify shallow clones during bootstrap.
-
-Both configure and bootstrap accept `BEXT_REPOSITORY_ROOT` to fetch from an
-alternate host or a local Git mirror.  See [alternate repositories and offline
-mirrors](INSTALL.md#alternate-repositories-and-offline-mirrors) for examples.
-
-# How manual selection works
-
-Build selection happens in three layers:
-
-1. `USE_*` options decide which dependency families are in scope.
-2. For in-scope packages, the default behavior is to use a suitable system
-   package if one is found and build a local copy only when needed.
-3. `ENABLE_<pkg>=ON` or `OFF` overrides one package explicitly.
-
-Default `USE_*` values:
-
-* `USE_BRLCAD=ON`
-* `USE_BRLCAD_EXTRA=ON`
-* `USE_GDAL=ON`
-* `USE_QT=ON`
-* `USE_TCL=ON`
-* `USE_APPLESEED=OFF`
-* `USE_OSPRAY=OFF`
-
-`ENABLE_ALL=ON` changes step 2 by preferring local builds for packages in the
-active `USE_*` groups.  It does not turn on groups whose `USE_*` option is
-`OFF`.
-
-When `bext` is driven from a BRL-CAD build, `BRLCAD_COMPONENTS` can further
-narrow some BRL-CAD-related packages to only those needed by the requested
-component set.
-
-# Official profiles
-
-The supported configure entry points are:
-
-* `auto` - standard BRL-CAD-oriented profile using suitable system packages
-  when found
-* `bundled` - standard BRL-CAD-oriented profile with bundled/local builds
-  preferred for all active groups
-* `minimal` - core BRL-CAD profile without extras, GDAL, Qt, Tcl/Tk,
-  Appleseed, or OSPRay
-* `everything` - all current groups enabled with bundled/local builds
-  preferred throughout
-
-Use them like this:
-
+* Configure with CMake.  Individual components can be enabled or disabled, but the ENABLE_ALL flag is used to automatically turn on all the projects.  There are also USE_* variables that can enable or disable various groupings of components based on which specific application stacks the user wishes to support.
 ```sh
-cmake --preset auto
-cmake --preset bundled
-cmake --preset minimal
-cmake --preset everything
+cmake ../bext -DENABLE_ALL=ON
 ```
-
-Build using the preset's build directory:
-
+* Run the build process.
 ```sh
-cmake --build build/auto --config Release --parallel 8
-```
-
-# Raw configure equivalents
-
-`auto`:
-
-```sh
-cmake ../bext -DCMAKE_BUILD_TYPE=Release
-```
-
-`bundled`:
-
-```sh
-cmake ../bext -DENABLE_ALL=ON -DCMAKE_BUILD_TYPE=Release
-```
-
-`minimal`:
-
-```sh
-cmake ../bext \
-  -DUSE_BRLCAD_EXTRA=OFF \
-  -DUSE_GDAL=OFF \
-  -DUSE_QT=OFF \
-  -DUSE_TCL=OFF \
-  -DCMAKE_BUILD_TYPE=Release
-```
-
-`everything`:
-
-```sh
-cmake ../bext \
-  -DENABLE_ALL=ON \
-  -DUSE_APPLESEED=ON \
-  -DUSE_OSPRAY=ON \
-  -DCMAKE_BUILD_TYPE=Release
-```
-
-# Build outputs
-
-By default, `CMAKE_INSTALL_PREFIX` is the build directory.  `bext` creates two
-output trees under that prefix:
-
-* `install/` - files intended to be bundled with downstream software
-* `noinstall/` - build-only tools and compile-time-only assets
-* `bext-install-manifest.json` - relative file classifications and the
-  platform metadata needed by downstream staging builds
-
-The normal build finalizes bundled binaries after all dependency install steps.
-It uses `strclear` and, where available, `plief` to remove stale build paths and
-normalize RPATH-bearing files before writing the manifest.  Consumers should
-continue to treat `install/` as read-only and perform their own staging-specific
-path and RPATH edits on copied files.
-
-The normal build also generates a dependency graph in the build directory as
-`bext.dot`.  When Graphviz `dot` is available, the build also emits rendered
-forms such as `bext.svg`, `bext.png`, and `bext.pdf`.
-
-When BRL-CAD consumes a `bext` build, `BRLCAD_EXT_DIR` should point at the
-parent directory containing both `install/` and `noinstall/`.
-
-# Using the build outputs with BRL-CAD
-
-If you used the `auto` preset, `BRLCAD_EXT_DIR` should be `../bext/build/auto`.
-Configure BRL-CAD with:
-
-```sh
-git clone https://github.com/BRL-CAD/brlcad
-mkdir brlcad_build
-cd brlcad_build
-cmake ../brlcad -DBRLCAD_EXT_DIR=../bext_build -DCMAKE_BUILD_TYPE=Release
 cmake --build . --config Release --parallel 8
 ```

-If you built Qt in `bext`, also enable Qt in BRL-CAD:
+Note that if you know you are going to build most or all of the component projects you can immediately populate all submodules when performing the clone:

 ```sh
-cmake ../brlcad \
-  -DBRLCAD_EXT_DIR=../bext_build \
-  -DBRLCAD_ENABLE_QT=ON \
-  -DCMAKE_BUILD_TYPE=Release
+git clone --recursive https://github.com/BRL-CAD/bext
 ```

-# More information
+This is primarily useful if you want to do all the downloading at once up front or you are preparing to work in an environment without an internet connection.
+
+A word of caution - full cloning of all the repository contents can be time, bandwidth and space intensive.  To help alleviate this a bit, you can add -DGIT_SHALLOW_CLONE=ON to the CMake configure, or if you're pre-cloning all repositories ahead of time use --depth=1 option with the above recursive clone.  Be aware that shallow clones have some limitations that make them unsuitable for much other than compiling (updating to newer versions of submodules won't work, for example) so shallow clones aren't recommended for development.
+
+# USE_* Options
+
+A complete ENABLE_ALL build of all components in this repository is a *very* large build, and developers not needing some subset of the components may wish to avoid paying the price of building *all* submodules.  That is why the USE_* options are defined - ENABLE_ALL will only enable those submodules that indicate they are used by at least one active USE_* option.  By default, USE_BRLCAD, USE_BRLCAD_EXTRA, USE_GDAL and USE_TCL are enabled as they collectively define the most common set of dependencies used by a standard BRL-CAD build.  However, if a developer is building BRL-CAD without terrain support and without Tcl/Tk support, setting USE_GDAL and USE_TCL to OFF will skip compilation of those submodules.  Available USE_* options are:
+
+* USE_BRLCAD - Core BRL-CAD dependencies always needed to build BRL-CAD successfully.
+* USE_BRLCAD_EXTRA - Optional BRL-CAD dependencies.
+* USE_GDAL - Geospatial Data Abstraction Library and dependencies
+* USE_TCL - Tcl/Tk and associated packages
+* USE_QT - Qt - cross-platform software for creating graphical user interfaces
+* USE_APPLESEED - Physically-based global illumination rendering engine
+* USE_OSPRAY - Intel high performance ray tracing engine
+
+(For BRL-CAD components specifically, a more nuanced enable/disable decision can be made if the BRLCAD_COMPONENTS variable is set.  If the parent BRL-CAD build is only building a subset of the BRL-CAD target set, no all dependencies will be needed.)
+
+# Using the Build Outputs with BRL-CAD
+
+At the moment this repository and BRL-CAD's support of it are still experimental.
+To test it, the steps are as follows:
+
+* Clone the BRL-CAD repository
+```sh
+git clone https://github.com/BRL-CAD/brlcad
+```
+* Remove the internal 3rd party directories (be sure NOT to accidentally commit this change to the repository...)
+```sh
+cd brlcad && rm -rf misc/tools/ext src/other
+```
+* Make a build directory
+```sh
+cd .. && mkdir brlcad_exttest_build && cd brlcad_exttest_build
+```
+* Configure with CMake, specifying the path holding the bext output directory the BRLCAD_EXT_DIR variable to locate bext_output. Unless you have overridden the CMAKE_INSTALL_PREFIX of the bext build, it will be located in your home directory.  The bext_output directory should in turn contain install and noinstall folders.  If you also wish to test with Qt, you must currently enable that support in BRL-CAD as well.  (Note that the BRL-CAD configure process is responsible for staging the BRLCAD_EXT_DIR contents into the build directory, so it can take some time to complete...)
+```sh
+cmake ../brlcad -DBRLCAD_EXT_DIR=<your_bext_output_dir> -DBRLCAD_ENABLE_QT=ON
+```
+* Run the build process.
+```sh
+cmake --build . --config Release --parallel 8
+cmake --build . --target package --parallel 8
+```
+
+If all goes well, the final result should be a relocatable BRL-CAD archive
+including both the main BRL-CAD outputs and the products of this external
+dependencies repository.
+
+
+# About This Repository
+
+In broad, the structure of the source tree is two tiered - the top level directories each denote a specific dependency project (Tcl, Qt, GDAL, etc.).  Within that directory are found:
+
+* A reference (using git submodules) to a copy of the upstream source code
+* Our managing CMakeLists.txt file defining the logic for building that project
+* A <dirname>.deps file identifying a project's dependencies on other bext projects
+* Any patch files or other supporting resources not part of the upstream tree
+
+Sometimes third party libraries will depend on other third party libraries (for example, libpng's use of zlib) - when a bundled component that is a dependency of other bundled projects is enabled, the expectation is that the other bundled
+components will use our copy rather than system copies of those libraries.
+
+# Compilation-Only Tools
+
+Although most of the components here are intended for bundling with the eventual binary software distribution, there are some exceptions to that rule. A few of the projects (AStyle, patch, LIEF, etc.) target a different installation folder and are used only for compilation (for this repository and/or when bundling the results of building this repository with other applications.)
+
+There are also header-only "libraries" such as Eigen that are needed only for compilation, and do not need to be distributed with our packages.
+
+To figure out which projects are in these categories, check for a CMAKE_NOBUNDLE_INSTALL_PREFIX target being used by their top level CMakeLists.txt file managing the ExternalProject_Add build definition.

-
-An installed Xmin SDK can provide the X11 and OpenGL surface for bext's
-bundled Tk and Qt, allowing fully interactive automated GUI application testing
-in an environment that has neither X nor OpenGL.
-
-Set `BEXT_XMIN_ROOT` to select the standard Xmin profile:
-
-```sh
-cmake -S /path/to/bext -B /path/to/bext-build \
-  -DBEXT_XMIN_ROOT=/absolute/path/to/xmin-sdk \
-  -DENABLE_TCL=ON -DENABLE_QT=ON
-```
-
-The profile affects only Tk and Qt packages selected for a local build.  It
-does not enable a package excluded by `USE_*`, `BRLCAD_COMPONENTS`, or an
-explicit `DISABLE_*` setting.
-
-* Tk is configured with `--with-xmin` and bext's matching Tk patch.
-* Qt is built with the matching Xmin patch, the qxcb desktop-OpenGL profile,
-  and dependency audits that reject accidental host X11 or OpenGL linkage.
-
-The patches are maintained next to the dependency build logic as
-`tk/tk_xmin.patch` and `qt/qt_xmin.patch`.  They are tied to the exact Tk
-and Qt submodule revisions in this repository.  Updating either dependency
-therefore requires updating its patch; a stale patch fails during the patch
-step rather than silently producing a mixed build.
-
-The Xmin SDK must include toolkit-client support for Tk.  Qt additionally
-requires the Qt X11 compatibility client and client OpenGL support.  Normal
-system discovery is unchanged when `BEXT_XMIN_ROOT` is empty.
-
-Qt's installed package metadata retains an explicit dependency on Xmin.
-Downstream projects must therefore keep the same SDK discoverable with
-`Xmin_DIR` or `CMAKE_PREFIX_PATH`; configuration fails instead of falling back
-to host X libraries when that SDK is absent.
-
-## Advanced toolkit patch controls
-
-Unix builds may pass additional, semicolon-separated absolute patch paths in
-`TK_EXTRA_PATCHES`, plus additional Tk `configure` arguments in
-`TK_CONFIGURE_ARGS`.  `QT_EXTRA_PATCHES` provides the corresponding Qt
-hook.  `QT_XMIN_ROOT` remains available for manually supplied Qt Xmin patches.
-These low-level controls are not needed when `BEXT_XMIN_ROOT` selects the

-FindICU
-------
-
-.. versionadded:: 3.7
-
-Find the International Components for Unicode (ICU) libraries and
-programs.
-
-This module supports multiple components.
-Components can include any of: ``data``, ``i18n``, ``io``, ``le``,
-``lx``, ``test``, ``tu`` and ``uc``.
-
-Note that on Windows ``data`` is named ``dt`` and ``i18n`` is named
-``in``; any of the names may be used, and the appropriate
-platform-specific library name will be automatically selected.
-
-.. versionadded:: 3.11
-  Added support for static libraries on Windows.
-
-This module reports information about the ICU installation in
-several variables.  General variables::
-
-  ICU_VERSION - ICU release version
-  ICU_FOUND - true if the main programs and libraries were found
-  ICU_LIBRARIES - component libraries to be linked
-  ICU_INCLUDE_DIRS - the directories containing the ICU headers
-
-Imported targets::
-
-  ICU::<C>
-
-Where ``<C>`` is the name of an ICU component, for example
-``ICU::i18n``; ``<C>`` is lower-case.
-
-ICU programs are reported in::
-
-  ICU_GENCNVAL_EXECUTABLE - path to gencnval executable
-  ICU_ICUINFO_EXECUTABLE - path to icuinfo executable
-  ICU_GENBRK_EXECUTABLE - path to genbrk executable
-  ICU_ICU-CONFIG_EXECUTABLE - path to icu-config executable
-  ICU_GENRB_EXECUTABLE - path to genrb executable
-  ICU_GENDICT_EXECUTABLE - path to gendict executable
-  ICU_DERB_EXECUTABLE - path to derb executable
-  ICU_PKGDATA_EXECUTABLE - path to pkgdata executable
-  ICU_UCONV_EXECUTABLE - path to uconv executable
-  ICU_GENCFU_EXECUTABLE - path to gencfu executable
-  ICU_MAKECONV_EXECUTABLE - path to makeconv executable
-  ICU_GENNORM2_EXECUTABLE - path to gennorm2 executable
-  ICU_GENCCODE_EXECUTABLE - path to genccode executable
-  ICU_GENSPREP_EXECUTABLE - path to gensprep executable
-  ICU_ICUPKG_EXECUTABLE - path to icupkg executable
-  ICU_GENCMN_EXECUTABLE - path to gencmn executable
-
-ICU component libraries are reported in::
-
-  ICU_<C>_FOUND - ON if component was found; ``<C>`` is upper-case.
-  ICU_<C>_LIBRARIES - libraries for component; ``<C>`` is upper-case.
-
-ICU datafiles are reported in::
-
-  ICU_MAKEFILE_INC - Makefile.inc
-  ICU_PKGDATA_INC - pkgdata.inc
-
-This module reads hints about search results from::
-
-  ICU_ROOT - the root of the ICU installation
-
-The environment variable ``ICU_ROOT`` may also be used; the
-ICU_ROOT variable takes precedence.
-
-The following cache variables may also be set::
-
-  ICU_<P>_EXECUTABLE - the path to executable <P>; ``<P>`` is upper-case.
-  ICU_INCLUDE_DIR - the directory containing the ICU headers
-  ICU_<C>_LIBRARY - the library for component <C>; ``<C>`` is upper-case.
-
-.. note::
-
-  In most cases none of the above variables will require setting,
-  unless multiple ICU versions are available and a specific version
-  is required.
-
-Other variables one may set to control this module are::
-
-  ICU_DEBUG - Set to ON to enable debug output from FindICU.

+FindICU
+-------
+
+.. versionadded:: 3.7
+
+Find the International Components for Unicode (ICU) libraries and
+programs.
+
+This module supports multiple components.
+Components can include any of: ``data``, ``i18n``, ``io``, ``le``,
+``lx``, ``test``, ``tu`` and ``uc``.
+
+Note that on Windows ``data`` is named ``dt`` and ``i18n`` is named
+``in``; any of the names may be used, and the appropriate
+platform-specific library name will be automatically selected.
+
+.. versionadded:: 3.11
+  Added support for static libraries on Windows.
+
+This module reports information about the ICU installation in
+several variables.  General variables::
+
+  ICU_VERSION - ICU release version
+  ICU_FOUND - true if the main programs and libraries were found
+  ICU_LIBRARIES - component libraries to be linked
+  ICU_INCLUDE_DIRS - the directories containing the ICU headers
+
+Imported targets::
+
+  ICU::<C>
+
+Where ``<C>`` is the name of an ICU component, for example
+``ICU::i18n``; ``<C>`` is lower-case.
+
+ICU programs are reported in::
+
+  ICU_GENCNVAL_EXECUTABLE - path to gencnval executable
+  ICU_ICUINFO_EXECUTABLE - path to icuinfo executable
+  ICU_GENBRK_EXECUTABLE - path to genbrk executable
+  ICU_ICU-CONFIG_EXECUTABLE - path to icu-config executable
+  ICU_GENRB_EXECUTABLE - path to genrb executable
+  ICU_GENDICT_EXECUTABLE - path to gendict executable
+  ICU_DERB_EXECUTABLE - path to derb executable
+  ICU_PKGDATA_EXECUTABLE - path to pkgdata executable
+  ICU_UCONV_EXECUTABLE - path to uconv executable
+  ICU_GENCFU_EXECUTABLE - path to gencfu executable
+  ICU_MAKECONV_EXECUTABLE - path to makeconv executable
+  ICU_GENNORM2_EXECUTABLE - path to gennorm2 executable
+  ICU_GENCCODE_EXECUTABLE - path to genccode executable
+  ICU_GENSPREP_EXECUTABLE - path to gensprep executable
+  ICU_ICUPKG_EXECUTABLE - path to icupkg executable
+  ICU_GENCMN_EXECUTABLE - path to gencmn executable
+
+ICU component libraries are reported in::
+
+  ICU_<C>_FOUND - ON if component was found; ``<C>`` is upper-case.
+  ICU_<C>_LIBRARIES - libraries for component; ``<C>`` is upper-case.
+
+ICU datafiles are reported in::
+
+  ICU_MAKEFILE_INC - Makefile.inc
+  ICU_PKGDATA_INC - pkgdata.inc
+
+This module reads hints about search results from::
+
+  ICU_ROOT - the root of the ICU installation
+
+The environment variable ``ICU_ROOT`` may also be used; the
+ICU_ROOT variable takes precedence.
+
+The following cache variables may also be set::
+
+  ICU_<P>_EXECUTABLE - the path to executable <P>; ``<P>`` is upper-case.
+  ICU_INCLUDE_DIR - the directory containing the ICU headers
+  ICU_<C>_LIBRARY - the library for component <C>; ``<C>`` is upper-case.
+
+.. note::
+
+  In most cases none of the above variables will require setting,
+  unless multiple ICU versions are available and a specific version
+  is required.
+
+Other variables one may set to control this module are::
+
+  ICU_DEBUG - Set to ON to enable debug output from FindICU.

+FindPNG
+-------
+
+Find libpng, the official reference library for the PNG image format.
+
+Imported targets
+^^^^^^^^^^^^^^^^
+
+.. versionadded:: 3.5
+
+This module defines the following :prop_tgt:`IMPORTED` target:
+
+``PNG::PNG``
+  The libpng library, if found.
+
+Result variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project:
+
+``PNG_INCLUDE_DIRS``
+  where to find png.h, etc.
+``PNG_LIBRARIES``
+  the libraries to link against to use PNG.
+``PNG_DEFINITIONS``
+  You should add_definitions(${PNG_DEFINITIONS}) before compiling code
+  that includes png library files.
+``PNG_FOUND``
+  If false, do not try to use PNG.
+``PNG_VERSION_STRING``
+  the version of the PNG library found (since CMake 2.8.8)
+
+Obsolete variables
+^^^^^^^^^^^^^^^^^^
+
+The following variables may also be set, for backwards compatibility:
+
+``PNG_LIBRARY``
+  where to find the PNG library.
+``PNG_INCLUDE_DIR``
+  where to find the PNG headers (same as PNG_INCLUDE_DIRS)
+
+Since PNG depends on the ZLib compression library, none of the above
+will be defined unless ZLib can be found.

-Itk in bext
-===========
-
-Tcl 8.6.18 already bundles Itcl 4.3.7, so bext deliberately has no separate
-Itcl project.  Itk is not part of either source distribution, so the bundled
-stack builds Itk from its own upstream repository after Tcl and Tk.  A system
-Tcl/Tk stack must already provide Itcl and Itk; bext never builds Itk against
-system Tcl/Tk.
-
-Itk cannot be built from installed public headers alone.  Its implementation
-includes Tcl's private tclInt.h and Itcl's private itclInt.h and directly uses
-the corresponding internal structures and entry points.  The Itk build must
-therefore use the private headers and stubs from the exact Tcl/Itcl sources it
-accompanies.  Bext supplies the standard install-sh helper omitted from the Itk
-repository.  On Windows, explicit Tcl, Tk, and Itcl source directories are
-passed to nmake.  On Unix-like platforms, upstream's generated TEA configure
-logic gets the corresponding source locations from the bundled configuration.
-
-Upstream's generic Windows TEA install target copies only ``*.tcl`` library
-files.  Itk also needs its ``*.itk`` class definitions and ``tclIndex`` at
-runtime, so bext extends the nmake install target to copy them and verifies the
-complete script set before accepting the install.
-
-Itk itself makes no direct Xlib calls: all of its window-system interaction
-goes through Tk stubs.  Upstream's TEA configuration nevertheless adds the
-host X library to Itk.  Bext suppresses that unnecessary dependency so Itk
-uses the X implementation selected by its matching Tk build and does not mix
-two incompatible X ABIs in builds such as the Xmin test configuration.
-
-Itk's own nominal Itcl 4.1 requirement is not sufficient: its upstream suite
-has seven failures with Itcl 4.1.0, involving private/protected components and
-destroyed-component cleanup, while all 100 tests pass with Itcl 4.1.1.  Bext
-therefore retains 4.1.1 as Itk's stub and package-index floor.
-
-BRL-CAD has a stronger system-stack requirement.  With Tcl/Tk 8.6.18, Itcl
-4.1.1, 4.1.2, and 4.2.3 fail the Tk-first Iwidgets baseline because they lack
-Itcl 4.3.0's workaround for Tcl 8.6.15's `Tcl_NewObjectInstance` behavior.
-The complete baseline passes with Itcl 4.3.0 and Itk 4.2.3, so bext requires
-Itcl 4.3.0 or newer before accepting a system stack.
-
-System selection is all-or-nothing: Tcl must load Itcl 4.3.0 or newer, and its
-package path must advertise Itk 4.2.3 or newer before bext accepts the matching
-system Tk.  Itk detection asks Tcl's package handler to index available versions
-without executing the selected package's load script, enforcing the floor on
-headless builders without trying to create a Tk window.  If either extension is
-missing or too old, bext selects the complete bundled stack.
-
-The bundled Itk revision reports version 4.2.7 and includes the upstream August
-2024 release plus subsequent Windows, Tcl/Tk 9, warning, and TEA maintenance.
-The complete upstream suite and BRL-CAD GUI baseline pass with the bundled
-Itcl under Xmin using the Xmin-compatible Tk build.
