I understand the rationale, however at the moment the pure Makefile approach also installs the .pc files. This means there needs to be a string replacement when installing from Makefile otherwise it's completely broken there. Is there a better way of detecting the lib64 component?

I missed that the Makefile approach stole CMake vars in that approach, will update the patch so both ways are fixed.
