Fixed bug 3862 - Install is broken when adding SDL2 to an existing CMake project

Steve Robinson

In my existing CMake project, I use add_subdirectory to add the source for SDL2.  This worked fine in 2.0.5, but now in 2.0.6 when I build the INSTALL CMake target, I get this error:

file INSTALL cannot find "D:/path/to/SDL2Config.cmake".
Call Stack (most recent call first):
  3rdparty/SDL2/cmake_install.cmake:32 (include)
  3rdparty/cmake_install.cmake:36 (include)
  cmake_install.cmake:32 (include)

To fix this, I changed line 1770 from this:
${CMAKE_SOURCE_DIR}/SDL2Config.cmake

To this:
${CMAKE_CURRENT_SOURCE_DIR}/SDL2Config.cmake
