Subject: [PATCH] replace CMAKE_SOURCE_DIR with PROJECT_SOURCE_DIR

This fix allows graaf to be used as an external dependency using
CMake's `FetchContent_Declare`. With `CMAKE_SOURCE_DIR`, CMake will
look for `packaging/graaf.pc` in the project using Graaf, rather than
Graaf itself. `PROJECT_SOURCE_DIR` is used over
`CMAKE_CURRENT_SOURCE_DIR` to maintain consistency within the
`CMakeLists.txt`.
