It looks like pkg-config's output is ignored:

$ pkg-config --libs cppunit
-L/usr/local/lib -lcppunit

I've just been looking at the CMake code and I guess finding CppUnit needs to be improved. The lookup is also not completely unreasonable, though. So I am wondering whether the build system even used pkg-config at all in your case? If Cppunit not detected via pkg-config so the version couldn't be checked. shows up in the configuration logs then that's not the case and it had to resort to find_library. You can set CPP_UNIT_LIB and CPP_UNIT_INCLUDE_DIR to workaround this for now.

I've just pushed a potential fix (https://github.com/Martchus/cpp-utilities/commit/5ebbd0eb3f72510d1b1678b967ce4acce17914cd) so you might try building the latest commit on GitHub.
