CMake config file

[ssrlive]

CMake configure file ready.

Can we also add test and coverage targets? That would be necessary if we want to replace the GNU Makefiles.

[ssrlive]

I don't know how to do that. Can you continue the work?

@ssrlive commented on the current CMake support status in #48; I am moving this here since there is no official CMake support in gc and any existing issues w/ CMake support are related to this PR.

Here is the comment:

test it on Windows / Linux / macOS, all the Release buildings are failed.

Also @ssrlive , I can't provide CMake support. The GNU make solution works fine. I am happy to merge a working CMakeList.txt, but as I mentioned earlier, I will require it to support build, text and coverage runs in order to accept the PR.

If that continues to be an issue for you, I am also happy to open a ticket that asks for CMake support and to tag it with a help-wanted tag.

Couldn't you provide this CMakeLists.txt besides the regular Makefile? There's no harm in having both, even though CMake can generate a Makefile, you usually don't do this within the project directory.

Having CMake support would make it much easier to integrate gc into other projects e.g. using git submodules.

@mupfdev, misunderstanding: as mentioned in the previous comment I'd be happy to merge a CMakeLists.txt to this project but it would need to have feature parity with the existing Makefile.
