Description Ethan Lee 2020-04-28 16:21:35 UTC 
When using SDL2-devel-2.0.12-mingw with CMake, builds will fail to start, only producing a mysterious "*** target pattern contains no '%'.  Stop."

I found out that the "if(NOT TARGET SDL2::SDL2)" block added in 2.0.12 is the root cause. Deleting this entirely gets builds to work again.

You can test this with both FAudio and FNA3D:

https://github.com/FNA-XNA/FAudio
https://github.com/FNA-XNA/FNA3D

Both builds are as simple as `mingw32-cmake .. && mingw32-make`, they should depend on nothing more than SDL2. I tested this on CentOS with the files provided by libsdl.org as well as Fedora's built-in mingw32/64-SDL2 packages.
