Allow specifying the library path completey
https://gitlab.gnome.org/GNOME/evolution-etesync/-/blob/master/CMakeLists.txt#L60
Correct me if I'm wrong, but AFAICT it's currently only possible to specify the library path suffix, ie lib${LIB_SUFFIX}. However on debian/ubuntu systems, due to the multiarch spec the correct library dir isn't something like lib64
but rather something like x86_64-linux-gnu
.
Request: allow specifying the full library path, so packagers don't have to hack this after the fact.
