[CMake] feedback on fortran support

[Daniel Franke]

Hi all.

After years of automake, I only recently starting looking into CMake. Setting 
up a multi-language project (C/C++/Fortran) was simple and everything just 
works. Impressive!

Two nitpicks/suggestions:

 1.
As CheckCSourceCompiles and CheckCXXSourceCompiles macros are available, one 
would expect a CheckFortranSourceCompiles (and CheckFortranSourceRuns and 
CheckFortranCompilerFlag and ...), but they are missing. Deriving the 
respective macro for Fortran based on the C/C++ files was very easy, so it's 
attached to this mail. Any chance to include it (or something like it) in the 
next release?

 2.
Fortran does not have any concept of preprocessing. However, by convention, 
files with a capital suffix (.F, .FOR, .FPP, .F90, F03, ...) are preprocessed, 
usually by a C-preprocessor. CMake does not take this into account and passes 
commandline definitions to any kind of fortran file. This is not exactly a 
bug, but maybe slightly inefficient.

Keep up the good work :)

Thanks

	Daniel
