Fixed bug 3867 - Can't find install_manifest.txt when running 'uninstall' target

Steve Robinson

When I try to build the 'uninstall' target in CMake when SDL2 is added to a subdirectory of my project, I get this error:

1>CMake Error at cmake_uninstall.cmake:2 (message):
1>  Cannot find install manifest:
1>  "D:/Code/sdl2-tutorial/_build/3rdparty/SDL2/SDL2-2.0.6/install_manifest.txt"

The install_manifest.txt is actually in the top-level binary directory, not the project-specific binary directory.

To fix it, change all instances of:
CMAKE_CURRENT_BINARY_DIR

To:
CMAKE_BINARY_DIR

In:
cmake_uninstall.cmake.in
