SDL2 CMake config package

This package is intended for distributions that do not provide an SDL2 CMake package.

Usage

This package does not build nor install SDL2, but instead installs an SDL2::SDL2 target for use in CMake scripts. So it expects the SDL2 library to already be installed.

Rough description:

• CMake configure and generate to ensure SDL2 can be found.
• CMake build and install.
• Use find_package(SDL2) and target_link_libraries(${TARGET_NAME} SDL2::SDL2) in CMake scripts.
• It may also be possible to use add_subdirectory on this directory, and target_link_libraries(${TARGET_NAME} SDL2).

Note that there is no attempt to provide components -- I only added features that I needed.

Purpose

CMake does not provide a SDL2 package by default. Distributions also may not provide one.

It may also used for bridging header #include directives between <SDL*.h> and <SDL2/SDL*.h>. This may become necessary because there is no universal install path. For example, Emscripten usees the former whereas Debian uses the latter. Source code may also use either.
