Possibly fixed bug 2250 - Cmake: SDL2 Doesn't install DLLs on Windows

ernest.lee

[Exec] CMake Error at cmake_install.cmake:151 (FILE):
[13:37:43][Exec]   file INSTALL cannot find
[13:37:43][Exec]   "C:/TeamCity/buildAgent/work/2e3d17a492e75daf/Build/libSDL2.so".

The cmake INSTALL project doesn't work because it uses Linux so shared library paths. Windows uses dlls and I think cygwin also uses dlls. I've included this patch. Can you check if it works?
