  Message : Fix building X11 tests on PE targets Link libxkbcommon_x11_internal with libxkbcommon_test_internal, rather than libxkbcommon. This avoids some tests linking with both libxkbcommon_test_internal and libxkbcommon, which causes duplicate symbol problems on PE targets (e.g. Cygwin) (as all the symbols from libxkbcommon are pulled in at link time, which clash with libxkbcommon_test_internal)
