i want to include gtk dependency libraries with gtk itself. but 
followings was error-prone.

I wondered why this brute-force based method doesn't work with cmake.
it complains it isn't from project so it can't compile. what a mess. 
cmake, this is not what you need to care for!
how we can deceive cmake so that i can work without problem?
