This is good advice, however, in most cases, since you're using
pkgconfig directly (which is not the recommended way), that will cause
more failure.  Best thing to do is to create/find a cmake module for
each of those packages, that might use pkgconfig for help finding the
library, but that doesn't just use what it returns verbatim.
