CMake build system

Hi!

It will be good to have CMake based build system for usearch. CMake is cross-platform build system, that allows quite easy build and install usearch

PS If appricated i can create merge request with cmake build system

Thanks for the suggestion. From my personal perspective, the problem with CMake is the integration with Microsoft Visual Studio is not very good, or more accurately I found it so difficult to use that I gave up. I use MSVS as my primary development environment, and recently I spent a few days trying to figure out CMake in the hope that this would make cross-platform development easier. I found CMake is quite easy, but MSCS-CMake integration to be very unfriendly. In the end, I decided it was easier to write my own Python scripts to generate Makefiles from .vcxproj files. There is a related discussion here for how I tried to solve the problem for MUSCLE: https://github.com/rcedgar/muscle/wiki/Design-of-Makefiles-and-Visual-Studio-project-build
