Summary:                    CMake Does Not Use -isystem with GCC on OS X
Description: 
On OS X with the GCC compiler, CMake does not pass the -isystem flag to build
commands for libraries configured with SYSTEM. For example, if target
'cmake_test' has an include added as 'target_include_directories( cmake_test
SYSTEM PRIVATE ${PNG_INCLUDE_DIRS} )', -isystem will not be added on OS X with
GCC.


Steps to Reproduce: 
Use the 'target_include_directories' command with the SYSTEM option on OS X with
GCC.
