[CMake] Fortran support bugs?

[yardbird]

Hello,

I would like to use CMake as a build system for a Fortran project of my 
research group.

The problems I'm experiencing are quite various, but I think I've tracked them 
down to a single cause. In the specific case, which I'm attaching as a 
compressed archive, CMake runs fine, but when launching make it hangs at the 
dependency scanning phase. With other Fortran projects, CMake detects bogus 
dependencies, which do not exist and have strange names. These strange names 
helped me to identify the probable cause of the bug, since such names are 
taken from comments in the source code: they consist of portion of phrases, 
name, adjectives, etc.

I think CMake is confused when it finds the "USE" keyword somewhere in Fortran 
comments, and it is tricked into thinking that the keyword is specifying some 
dependency even if it is placed inside a comment. Indeed, by erasing all 
comments in source files, usually the build is performed successfully.

Does this make any sense? I would really like to use CMake for these Fortran 
projects, since I'm already using it heavily in my C/C++ projects and I love 
it.

Thanks and best regards,

  Francesco.
