cmake and fortran

cmake and fortran

Hi,
as lapack is moving to cmake as build system,
I started to playing with cmake and I suspect no one
tried before cmake and fortran together on cygwin.

The definition file
/usr/share/cmake-2.6.4/Modules/Platform/CYGWIN-g77.cmake
is clearly wrong. It tries to build libxxx.dll and so on.

Attached the one that I am currently using, copied and modified
from CYGWIN-g77.cmake that seems right.

Could the cmake maintainer give a check and eventually 
report the issue upstream ?

Regards
Marco

I'm not the cmake maintainer, but could you try Ports' cmake-2.8.1-11
and see if that's any better?

2.8.1-11 looks much better.
I see that the same structure is used for all GNU compiler

on
/usr/share/cmake-2.8.1/Modules/Platform

CYGWIN-GNU-C.cmake    
CYGWIN-GNU-Fortran.cmake  
CYGWIN-GNU-CXX.cmake  

all refer to common structure in
CYGWIN-GNU.cmake
