demo's not compiling, posix linker args end up bad

When following the instructions to generate the Ninja files with CMake, the resulting builds fail as the linker args generated try to reference a non-existant library "Threads::Threads". Including the "FindThreads" CMake module fixes this issue. It looks supported on CMake 2.8 all the way up to the current release. The demos now easily build following the instructions.
