Add support for CLbundler created LibPack

* New 'UseLibPack' cmake file sets CMAKE_PREFIX_PATH so that find_package
  can be used for most packages.
* Mimic fc_wrap_cpp defined in other 'UseLibPack' files. Some file
  dependencies did not get set correctly otherwise.
* OCE 0.16 does not have Standard_ctype.hxx
* shfolder.h can't be used with Win SDK 7.0
