Given its looong existence and to avoid disruption in existing workflows, PROJ_LIB will still work for the time being, and should probably be kept functional at least for the PROJ 10 series. A runtime debug message is logged (PROJ_DEBUG>=2) if using PROJ_LIB to point to the recommended PROJ_DATA. The PROJ_LIB_ENV_VAR_TRIED_LAST CMake option is renamed consistently to PROJ_DATA_ENV_VAR_TRIED_LAST and a CMake warning is emitted when the old name is used (in which case the value of PROJ_LIB_ENV_VAR_TRIED_LAST is used for PROJ_DATA_ENV_VAR_TRIED_LAST) The rational for this change is: - PROJ_LIB is a misleading name. Some users believe it is related to the loading of the PROJ executable library. - to align nicely with GDAL_DATA since they are about the same thing.
