Fixed bug 5044 - CMake messes up hidapi path when project directory contains spaces

Eric Jing

When the project directory path contains spaces, CMake butchers the include path for the hidapi files.

I traced the problem to the cmake/sdlchecks.cmake file at line 1091, which sets flags for the build process. I surrounded the problem flag with double quotes, shown below, and CMake works with spaces in the project directory path.
