[CMake] CMAKE_OSX_SYSROOT and find_XXX

[Michael Wild]

Hi all

I'm a bit struggling with using CMAKE_OSX_SYSROOT. The problem is that  
find_library and cohorts do not consider CMAKE_OSX_SYSROOT at all,  
thus reporting bogus paths.

I think that find_library, find_path and find_file (did I forget any?)  
should honour CMAKE_OSX_SYSROOT and treat it as if CMAKE_PREFIX_PATH  
and CMAKE_FRAMEWORK_PATH were set to "${CMAKE_OSX_SYSROOT}/usr" and "$ 
{CMAKE_OSX_SYSROOT}/Library/Frameworks:${CMAKE_OSX_SYSROOT}/System/ 
Library/Frameworks", respectively.

Should I create a bug for this?
