Thanks for bisecting!

That change may have accidentally affected the preprocessor definitions
sent to the Fortran compiler.  The error message you're seeing is actually
coming from the compiler trying to use the module, so SOMEDEF must be
getting defined.  However, without seeing your CMake code I cannot
determine how.

Can you provide a minimal source tarball that exhibits the problem?

Thanks,
