Commit fe6f62e6ce6cdf2583b513a4b39ec4f3d93dec87
2021-02-10T15:17:02
Add ALIAS targets to all installed SDL2 targets This provides a linking interface that matches the one available when `find_package()` is used, by aliasing all of SDL's public targets into the SDL2:: namespace. Thus, dependees link to the same-named targets regardless of how SDL was acquired. This approach permits the use of wrappers around CMake's FetchContent API such as https://github.com/cpm-cmake/CPM.cmake
