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.
