-# This is based on the logic generated by CMake for EXPORT, but customized for
-# use with ExternalProject:
-#
-# https://cmake.org/cmake/help/latest/module/ExternalProject.html
-#
-# The goal is to create an imported target based on the ExternalProject
-# information, and then append the necessary install logic to manage RPath
-# settings in the external projects as if the external files were built by the
-# main CMake project.
-
-# TODO - need to rework this in a way that's compatible with the superbuild
-# pattern. Main BRL-CAD build won't have the ExternalProject_Add targets from
-# the superbuild, so we need another way to handle getting the necessary
-# info to the main build. Maybe useful:
-#
https://gitlab.kitware.com/cmake/community/-/wikis/doc/tutorials/How-to-create-a-ProjectConfig.cmake-file
-
-# The catch to this is that the external project outputs MUST be built in a way
-# that is compatible with CMake's RPath handling assumptions. See
-#
https://stackoverflow.com/questions/41175354/can-i-install-shared-imported-library
-# for one of the issues surrounding this - file(RPATH_CHANGE) must be able to
-# succeed, and it is up to the 3rd party build setups to prepare their outputs
-# to be ready. The key variable CMAKE_BUILD_RPATH comes from running the
-# function cmake_set_rpath, which must be available.
