patch-Charm_CMakeLists.txt

Munge (effectively) -L/usr/local/lib into the link lines.

QtKeyChain's cmake config lists the libraries it depends on:
 - a bunch of Qt5 libraries, which are imported targets, and hence
   already have full paths for CMake
 - other libraries, like libsecret-1, gio, gobject .. which are not
   set up as imported targets; these are not found at link-time unless
   the directory is added to -L. They do have a pkg-config file,
   so we'll look for (only) libsecret-1 and just add the directory it
   lives in -- hopefully the other libraries live there too.

Error message otherwise:
