Summary: include_directories(SYSTEM) should promote
Description:
In some instances (possibly related to CMake version),
include_directories(SYSTEM ${foo}) has no effect.
Steps to Reproduce:
include_directories(${foo})
include_directories(SYSTEM ${foo})
Additional Information:
It appears that CMake ignores an include_directories(SYSTEM) for include
directories that already exist. This is more likely in large projects where e.g.
a top-level CMake file (or even a UseFoo.cmake) includes directories without
SYSTEM, and a leaf CMakeLists.txt does an include_directories(SYSTEM) of the
same directories.
I think it would be better following the expected behavior of
include_directories if, rather than ignore the directive if the directory is
already in include_directories, to 'promote' it to SYSTEM (probably without
changing the order).
