Summary:                    target_include_directories(tgt SYSTEM PUBLIC foo)
adds include path with -I instead of -isystem
Description: 
With the ninja generator and AppleClang on OS X the include flag -I is used
instead of -isystem when include directories are added to specific targets

A global include_directories(SYSTEM headers) uses the correct -isystem flag

Steps to Reproduce: 
mkdir tmp && cd tmp
touch main.cpp
cat << EOF > CMakeLists.txt
cmake_minimum_required(VERSION 3.2)
project(test)
add_executable(main main.cpp)
target_include_directories(main SYSTEM PUBLIC include)
EOF
mkdir build && cd build
cmake -G Ninja ..
grep build.ninja -e "-I../include"

Additional Information: 
-- The C compiler identification is AppleClang 6.0.0.6000057
-- The CXX compiler identification is AppleClang 6.0.0.6000057
