There are varying degrees of dynamic handling of the things to be used:

a) plain specific library filenames [easiest but most hard-coded/wrong]
b) using results (variables) of a manual find_library() supplied with
   potential names of the library to be found [much better]
c) using find_package() with either a related Find*.cmake module
   or (in Config mode) the Config file as provided by the installed
   (or in-tree) library package [best?]

Since the code currently is using a), I'm somewhat less astonished
that it does not work ;)

So I'd recommend at least using b), or possibly c) if it can be achieved
easily (existing package with its configuration exported, or Find module
sufficiently easily available).
But I'm sure some people would say "always use c)".

HTH - anything else?
