cmake: use PROJECT_SOURCE_DIR instead of CMAKE_SOURCE_DIR

Use PROJECT_SOURCE_DIR instead of CMAKE_SOURCE_DIR, since when gnuradio4 is built as a dependency using FetchContent_Declare(), CMAKE_SOURCE_DIR points to the source of the application that depends on gnuradio4 instead of gnuradio4's source. Signed-off-by: Daniel Estévez <[email protected]>
