It didn't work at all because shared libs defined in CMake with add_library() need something like IMPORTED_IMPLIB (pointing to a .dll.a or .lib for th DLLs) set to link on Windows. But even with that it didn't work because the order of the libs is very important: it must be -lmingw32 -lSDL2main -lSDL -mwindows - but with normal add_library(SDL2::SDL2 SHARED IMPORTED) libs, SDL2 itself is always linked first. So I use an "INTERFACE" library (usually used for header-only libs), which doesn't implicitly/automatically link anything so I can specify the whole order of the linked libs. (SDL2::SDL2-static is completely untested)
