-Subject: [PATCH 2/3] Allow Manual Overriding of pkg-config Lib and Include
- Dirs
-
-When the `PCLIBDIR` or `PCINCDIR` is non-empty (either because we succeeded
-in removing the prefix, or because it was manually set), we don't need to
-perform the check. This lets us trust users who go to the trouble of setting
-a manual override, rather than still blindly failing the make.
-
-They'll still be prefixed with `${prefix}/` / `${exec_prefix}/` in the
-pkg-config file though.
