fpm project with C source; Intel compilers on Windows #486
Description
I was trying to build an fpm project with Intel compilers on Windows and was running into issue.
C:\Temp\test>fpm run --compiler ifort

C source is src/csource.c

c_compiler = 'icl'to https://github.com/fortran-lang/fpm/blob/master/src/fpm_compiler.f90#L341 and create a PR. But it wouldn't solve it, because icl syntax for 'compile-only, do not link', is icl /c file.c /Fofile.obj and that requires a change in https://github.com/fortran-lang/fpm/blob/master/src/fpm_backend.f90#L243. My understanding is that I should not add compiler specific flags to fpm_backend.f90.
