review FindBlueZ.cmake

[Alexander Neundorf]

Hi,

this file looks quite good.

Only comments:

* this part is unnecessary:
if ( BLUEZ_INCLUDE_DIR AND BLUEZ_LIBRARIES )
   # in cache already
   set(BlueZ_FIND_QUIETLY TRUE)
endif ( BLUEZ_INCLUDE_DIR AND BLUEZ_LIBRARIES )

since find_package_handle_standard_args() anyway only prints something if this 
output differs from the previous run

* the if(NOT WIN32) around the pkgconfig-stuff can be removed, if pkgconfig is 
not found, pkg_check_modules() simply does nothing

* the additional search paths for find_path() and find_library() should 
probably be given with HINTS, not with PATHS, so they are preferred over the 
standard directories (as we do it in most other find-modules)


Is git mv the right command to move a file from attic/ to modules/ with 
keeping history ?
(I think I heard that git doesn't have mv, so I'm confused)
