[CMake] fortran, modules and case

[Andrew Brydon]

Hi,
	I am trying to port a large existing fortran library to using cmake,  
and have come up against a problem with the use of inconsistent  
module cases in the code (this is permitted in fortran).

I believe the logic in the existing fortran dependancy scanner does  
not consistently change the case of modules. The .mod.proxy targets  
are sometimes changed to lower case, but at other times the case of  
the source code is used. I've attached a small example with two  
modules that use inconsistent module access and fail to compile with  
the latest cmake from cvs as follows

blanco:~/tmp/cmake_f90/_build/cmake2.4 abrydon$ make
Scanning dependencies of target hello_mods
make[2]: *** No rule to make target `hello1.mod.proxy', needed by  
`CMakeFiles/hello_mods.dir/main.o.requires'.  Stop.
make[1]: *** [CMakeFiles/hello_mods.dir/all] Error 2
make: *** [all] Error 2


I've attached a patch to cmDependsFortran.cxx which seems to fix the  
problem in both the simple example and the existing package.

thanks
	Andrew
