Description of problem: pkg-config metadata from mosquitto-devel is not consistent with install locations on an x86_64 system. It adds /usr/lib (only) to the library search path, but the actual libraries are installed on /usr/lib64. Version-Release number of selected component (if applicable): 1.6.15-1.el8 How reproducible: Steps to Reproduce: 1. pkg-config --libs libmosquitto Actual results: -L/usr/lib -lmosquitto Expected results: -L/usr/lib64 -lmosquitto or just -lmosquitto Additional info: "pkg-config --libs libmosquittocpp" has the same issue.
