CMake: get rid of Makefile and Ninja

[fufexan]

Fixes #153.

Addresses all the remaining points in the above issue.
@alerque mind testing this PR?

you should also update README for the new instructions.

I'd generally stick to libexec being in lib/ as from my experience on arch libexec/ isnt picked up.

-DCMAKE_INSTALL_LIBEXECDIR=/usr/lib should do the job, I think

It looks like some of the changes here were intended to make it possible to build and install hyprland-protocols separately and depend on it from the system (which is a good thing!), but somehow that's managed to break the current submodule arrangement. I haven't tried to build it separately yet (although that will be the preferred way to package this in the long term), but the previous CMake incantation that was finding and building it stopped working when run on this PR.

I think it's the add_subdirectory call that makes it not work, but could you give me some logs?

Yes. Maybe I've said it before, but I hate git submodules 😄

That latest force-push is a lot better.

Now the only differences between the previous release packaged for Arch (using Meson) and my current attempts with 1.3.0 plus this PR using generic CMake are that some of the hyprland-protocols things are not being installed. The subdirectory build does work to satisfy the dependency but it does not end up installing the pc file or protocol files for it. I haven't tested yet whether those are needed at run time. This result might actually be expected & correct in that those should only be vendored if using the subproject and only installed to the system if built and installed in their own right.

If the latter is the expected behavior then this PR might be 👍 go for launch.

Yes, the .pc file and the XML protocols are only needed when hyprland-protocols is a standalone package.
