Documentation on installing/setting up

[rishavs]

Hi

How would I go about using this library in my c99 code?
I didn't see any section in then docs on installing it, so could use the help.

I tried make, but make didn't have any target.
So then I created a build dir in the project root and the did cd build and cmake ..
This errored out however, as I apparantly do not have pthreads.

It will be good to have a section on installing qlibc and its dependencies on each platform.
