See the CMake 3.8 documentation on these two variables: https://cmake.org/cmake/help/v3.8/variable/PROJECT-NAME_SOURCE_DIR.html https://cmake.org/cmake/help/v3.8/variable/CMAKE_SOURCE_DIR.html Under normal circumstances, these two are identical. For sub-projects (i.e., when building UHD as part of something else that is also a CMake project), only the former is useful. There is no discernible downside of using UHD_SOURCE_DIR over CMAKE_SOURCE_DIR. This was changed using sed: $ sed -i "s/CMAKE_SOURCE_DIR/UHD_SOURCE_DIR/g" \ `ag -l CMAKE_SOURCE_DIR **/{CMakeLists.txt,*.cmake}` $ sed -i "s/CMAKE_BINARY_DIR/UHD_BINARY_DIR/g" \ `ag -l CMAKE_BINARY_DIR **/{CMakeLists.txt,*.cmake}` At the same time, we also replace the CMake variable UHD_HOST_ROOT (used in MPM) with UHD_SOURCE_DIR. There's no reason to have two variables with the same meaning and different names, but more importantly, this means that UHD_SOURCE_DIR is defined even in those cases where MPM calls into CMake files from UHD without any additional patches. Shoutout to GitHub user marcobergamin for bringing this up.
