Cmake: Fix including the wx libs for versions more complex than e.g. 3.1

In its wisdom, fedora doesn't emit '-L/usr/lib64' from wx-config --libs. Previously this was worked-around by using find_file(...libwx_baseu-3.1.so..." but this fails for e.g. libwxbase3u or with git versions in the name (and find_file doesn't do globs/regex). So use the standard 'find' instead.
