Migrate to CMake

[ivan-volnov]

Hi,

Thanks for the app. Works great!

I had a trouble to build it on FreeBSD 14.2 with Clang. It could not find libraries and failed to compile because of CRT.

So, I just migrated to CMake.

I believe CMake is much better to build the project anywhere.

You can accept it, if you wish.

I usually build it with gcc. I have no experience with clang and don't know if the CFLAGS in the Makefile are compatible with clang. I also don't have experience with cmake. Right now I don't really have time to learn new tools and compare them to make and gcc and would rather stick with make. One reason is also that I use it with Arch Linux and there gcc and make are included in base-devel (used to install AUR-packages). I don't want to install new build-tools for such a small program but rather would like to use what is already preinstalled.

I am not sure but I think regarding missing libraries the program pkg-config (also in base-devel) is commonly used to find libraries on different systems. However, right now I also don't have time to deal with pkg-config although I probably should have used it from the start and should migrate my other programs to it. Sorry for not giving BSD enough love. I will fix it sometime. Or if you want you can integrate pkg-config into the Makefile. I am sure make should also work with BSD.
