Prefer non-empty prefixes when matching lib names (#11468)

Browse Source 
In cmComputeLinkInformation we match library names with a regular
expression, possibly extracting the 'lib' prefix.  The regex component
to match the prefix always allows an empty prefix to be matched, as in
"(lib|)".  Avoid every adding an empty prefix option earlier in the
regex, as in "(|lib|)", because it will be preferred and 'lib' will
never match.
