GLSMAC: reimplementing Alpha Centauri and Alien Crossfire

GLSMAC is an OpenGL and SDL2 reimplementation of Sid Meier's Alpha Centauri and Alien Crossfire. The current version heading is v0.3+. The first launch asks for the original installation path and loads its images and sounds. cmake -S . -B build -DCMAKE_BUILD_TYPE=Release && make -C build is the release build. Linux packages include CMake, SDL2, SDL2_image, FreeType, GLU, GLEW, ossp-uuid, and yaml-cpp. Windows builds use Visual Studio 2022.
