<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black">Hello,<o:p></o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black"><o:p> </o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black">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.<o:p></o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black"><o:p> </o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black">The problem is rather this:<o:p></o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black">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.
<o:p></o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black"><o:p> </o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black">(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.)<o:p></o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black"><o:p> </o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black">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.<o:p></o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black"><o:p> </o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black">But the crucial part is that CMake uses the settings for the GNU compilers.
<o:p></o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black"><o:p> </o:p></span></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black">So: Is it possible to instruct CMake to use the NAG-Fortran specific settings and if so, how do I do that?<o:p></o:p></span></p>
