Re: [Plplot-devel] Building plplot in Windows with Intel Fortran Compiler

[Jeremy N. <jrn...@gm...>]

Hi,

I had some time today and figured out the issue.  CMake found the Intel IFX
compiler first and it seemed to cause confusion about what type of compiler
was actually being used.  I worked around this by simply using set FC=ifort
and re-running CMake.  Was able to get everything I wanted built and tested
using the command line tools.

I'm guessing this is not a common use case, but if it happens to others it
might be worth updating the CMake files to handle both the Fortran
compilers that are installed from the Intel OneAPI tools.

Thanks,
Jeremy
