[question] How to generate custom content for PkgConfigDeps that is compatible with pkg_config

[jwillikers]

When migrating from pkg_config to PkgConfigDeps, custom content frequently breaks because it uses the fairly standard variable libdir but PkgConfigDeps defines this as libdir1. Would it be possible to change the default name to libdir when there is only one library directory? This would solve the issue in all cases that I've seen on CCI so far.

CCI issue: conan-io/conan-center-index#12890

• I've read the CONTRIBUTING guide.

Update, looks like we probably need to use libdir and includedir even when using multiple of such directories for dependencies which still expect to find those variables.

Hi @jwillikers! Sorry, I just realized this one.

I have a question about this issue. Regardless of changing libdir1 to libdir (the same for includedir), what about the cases that we're defining several includedirN and libdirN? Sorry for the basic question, but which is the use case to use that libdir and includedir?

Closing this issue as it was already solved by #13623

UPDATED: Released since Conan v2.0.8 (actually, it was since v2.0.7, but a bug appeared, and it was solved by the next one).
