This is even simplier !

Speaking of missing documentation, there may be a general confusion
due to some case-insensive cmake module. When one look at
FindLibXml2.cmake, which sets LIBXML2_LIBRARIES / LIBXML2_INCLUDE_DIR,
people may think that
setting MyPackage_DIR is equivalent to setting MYPACKAGE_DIR. This is
not the case and for example:

  find_package(CaSeSeNsItiVe)

will actually look for CaSeSeNsItiVeConfig.cmake and one has to set
CaSeSeNsItiVe_DIR.
