Summary0015502: Add color to Ninja output like with CMAKE_COLOR_MAKEFILE
DescriptionWith CMAKE_COLOR_MAKEFILE (default to ON) CMake creates target descriptions with colors.
This is great for human readability.

However, with the Ninja generator there is no such option, and CMake doesn't emit any color: the output is much harder to read by a human.

Would it be possible to add a CMAKE_COLOR_NINJA equivalent to CMAKE_COLOR_MAKEFILE, but for the Ninja generator?

IIRC ninja captures the output of all tools in its own streams so they don't have access to the terminal. Therefore if someone works on this the feature would have to be enabled by some explicit option or environment variable.

According to this https://groups.google.com/forum/#!topic/ninja-build/YaoHVrHh5zk [^] CMake can use the "description" rule variable with ANSI escape codes.

Re 0015502:0038477: Neat. However this will still require an option to explicitly enable because CMake has no way to know at generation time what kind of terminal will be used to run ninja.

This should actually be achievable by adding the compile flag `-fdiagnostics-color=always`, according to the Ninja developers: https://github.com/martine/ninja/issues/814 [^]

I've tested this on Debian 7.8 using GCC 5.1.0, CMake 3.2.2, and Ninja 1.5.3. It should work for Clang as well, but I have not yet been able to verify this.

I've now tested it with a recent Clang++3.7 build from the LLVM trunk, as well, and it seems to work.
