add pkg-config files for mumps libs

[minrk]

closes #104

This is only for the public libs. Is it needed for mumps_common and/or pord?

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

I can't seem to find the job artifacts, where should I look?

[minrk]

Not at all obvious, but here:

This works!

Run-time dependency dmumps_seq found: YES 5.6.2
Run-time dependency zmumps_seq found: YES 5.6.2
Run-time dependency cmumps_seq found: YES 5.6.2
Run-time dependency smumps_seq found: YES 5.6.2

and the tests pass.

I also confirm that linking against mumps-common seems unnecessary (TIL).

I wonder whether the suffix -seq is the right way to go, but this is consistent with how the library itself is packaged.

[minrk]

I was thinking matching the library name (_seq) rather than the package name (-seq) would be the least surprising, but I don't have strong feeling. What do you think?

[akhmerov]

Makes sense. I think this is good to go.

[minrk]

Thanks!

Btw, I don’t think this will generate correct confit files for windows.

[jcapriot]

when on windows, "/Library" needs to be append to prefix: There should also be a LIBRARY_PREFIX environment variable in conda-build recipes on windows that would point to this correct path

prefix = Path(os.environ.get("LIBRARY_PATH", os.environ["PREFIX"]))

[minrk]

I didn't realize pkg-config was a thing on Windows! This doesn't generate files for Windows at all.

If you know what they should be, a PR updating the script and adding it to bld.bat would be much appreciated.
