Make the ~/tone12/CMakeLists.txt your main CMake file (i.e. put the
project() command in there and all other commands that apply to the
whole project) and add a "add_subdirectory(src)" call, and then call
CMake with "cmake .." instead.

Also, the built-in commands, function and macro names are AFAIK
case-insensitive since the 2.6 days. I always use include_directories().
