CMake 3.0.2 is pretty old, and there were some find and other issues
for early CMake-3 versions.  I don't know whether any of those issues
are relevant to the issue you are discussing. Nevertheless, as an
experiment (and to make sure your eventual solution works for the
latest CMake) I would suggest you try building and using the latest
released version of CMake, 3.5.2, to see if that makes any difference.
