Is dependency('mpi') supposed to find the right wrappers?

[kentonwho]

I am a newbie trying to port an old Fortran MPI code to build with Meson. I am trying to use my install from Intel OneAPI, so I am telling meson to use ifx:

(base) wukenton@Lupky:~/dagswem$ cat intel.ini                                                                                                                                      
[binaries]
fortran = 'ifx'
[properties]
#fortran_args = ['-w', '-fPIE', '-fPIC']

I thought by declaring mpi as a dependency for a target, it would find the correct mpi wrapper based on the Fortran compiler to build the target. However, it just seems to find the gfortran wrapper and then use the regular ifx compiler to build, which obviously fails.

What am I missing?

At the very least, it appears we might have a bug in the intel MPI code we only look for the Intel specific tools with the pre-oneAPI compilers. I can write a quick patch if you want to test it?

[kentonwho]

Yes, that would be great!

#15260 will hopefully fix it
