The project uses
CMAKE_SOURCE_DIRto refer to the top level directory of the project, when it should be usingPROJECT_SOURCE_DIR.CMAKE_SOURCE_DIRrefers to the directory from which CMake was started.PROJECT_SOURCE_DIRrefers to the directory from whichproject(qaccordion)was called.It's not always the case that
CMAKE_SOURCE_DIRis the same asPROJECT_SOURCE_DIR. Ifqaccordionis included into another project, the variables are different.For instance, if
qaccordionis in another project likeother-project/external/qaccordion, then:CMAKE_SOURCE_DIRis/home/tay10r/other-project/PROJECT_SOURCE_DIRis/home/tay10r/other-project/external/qaccordion
