[CMake] MinGW-w64/MSYS2 (or Cygwin) and NAG Fortran - how to combine?

[Arjen Markus]

Hello,



In the PLplot project we are looking for a way to combine the MinGW-w64/MSYS2 platform (or Cygwin) with the NAG Fortran compiler. The reason for this is that both MinGW-w64/MSYS2 and Cygwin come with a nice repository of libraries, some of which we can use in the context of PLplot. The NAG Fortran compiler is a very nice, strict, compiler that is available for both Windows and Linux (and possibly other platforms as well). I know in principle how to combine NAG Fortran with the GCC tools, so this part of the combination is not the problem.



The problem is rather this:

If I start a console with MinGW-w64/MSYS2 or Cygwin I get an environment where all the libraries that I want can be found, but that environment is identified by CMake as "MinGW" or "Cygwin", so that the NAG Fortran specific settings are ignored.



(I store them in a file MinGW-NAG-Fortran.cmake, in analogy with all the other such files - a file Windows-NAG-Fortran.cmake does do the job for the "bare" Windows platform.)



The NAG Fortran compiler is selected, just like I want, instead of the gfortran compiler, as I define FC to be "nagfor" and I have expanded the PATH to include all the stuff for NAG Fortran.



But the crucial part is that CMake uses the settings for the GNU compilers.



So: Is it possible to instruct CMake to use the NAG-Fortran specific settings and if so, how do I do that?



Regards,



Arjen
