Modernize CMake build system (#1434)
These changes modernize the CMake build system to (hopefully) match newer best practices

* Library linking is simpler and more automatic because of using imported targets
* Multi-configuration builds should be supported (Ninja Multi-Config, Visual Studio, etc. generators)
* Clean up build options using cmake_dependent_option
* Let CMake do its job in more cases, like finding the math/dl libraries and detecting and enabling LTO support
* Remove platform-specific kludges like the Fedora/flatpak LTO workaround and a bunch of Windows stuff
* Simplify Windows static builds
* Consistent formatting

# The entire codebase quite reasonably does things like #include <SDL2/SDL.h> or <epoxy/gl.h>
# CMake apparently doesn't think you should be doing this, so just includes $PREFIX/include/packagename for a given
# package as include directories when using `target_link_libraries` with an imported target, this hacky function fixes
# that up so includes can keep working as they always did but we can still use fancy imported targets.
# This is stupid.
