This is expected to work. The custom command should be evaluated
during the build before CMake scans dependencies. I just tested
this case and it works for me.
Perhaps something about the actual content of gen.f90 prevents
CMake from picking up the module it generates. Can you post
its content here? Even better, can you provide a *minimal* but
complete source tarball that reproduces the problem?
