Hi Arjen:

I think you should be guided by what goes on for gfortran. For that compiler, 
relevant Platform files are called CYGWIN-GNU-Fortran.cmake and Windows-
GNU-Fortran.cmake Platform files for the Cygwin, and MinGW-w64/MSYS2
platforms.  Furthermore, in all the existing nagfor cases (Linux and Darwin), 
derive the nagfor-related name from the gfortran related name by replacing GNU-
Fortran by NAG-Fortran. Therefore, I suggest you try the names CYGWIN-NAG-
Fortran.cmake and Windows-NAG-Fortran.cmake for the two separate Platform
files you are trying to create for the Cygwin and
MinGW-w64/MSYS2 platforms.

I have a Platform file "Windows-NAG-Fortran.cmake" and that is used
correctly if I start the NAG Fortran environment (using the MinGW
Makefiles generator), but if I try the same with MinGWw-w64/MSYS2,
this file is clearly ignored - I see the compiler fail on a typical
GCC flag for creating shared libraries (the Platform file I added
takes care of that in the NAG Fortran environment and therefore the
build succeeds).

Hi Arjen:

Is the issue that you used the "Unix Makefiles" generator rather than
the "MSYS Makefiles" generator for the MinGW-w64/MSYS2 test?  I
believe you have found both generators work pretty well for this
platform, but in order to use your "Windows-NAG-Fortran.cmake" platform
file, you may find that the "MSYS Makefiles" generator is the one you
*must* use.

If you report back that experiment doesn't work, then we need a
knowledgable CMake developer to chime in here to let you know exactly
what Platform filename is correct for the nagfor compiler on the
MinGW-w64/MSYS2 platform for either/both the "Unix Makefiles" and
"MSYS Makefiles" generators.
