CMake: don't copy over modules with unsupported interfaces.

Browse Source 
If Python isn't found, or PythonQt isn't found, there is no point
in copying over the modules into the build tree; this may even be
misleading because the files are there, but won't work and this
will be noticed at runtime only.

Instead, skip the modules and explain why.
