cmake: Detecting C compile features - failed

[WANG-lp]

Hi,

When I try to use qrintf with cmake, I got following errors:

➜  cmake-build-debug git:(master) CC="/usr/local/bin/qrintf cc" cmake ..
-- The C compiler identification is GNU 8.1.0
-- Check for working C compiler: /usr/local/bin/qrintf
-- Check for working C compiler: /usr/local/bin/qrintf -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Detecting C compile features
-- Detecting C compile features - failed

-- Looking for pthread_create in pthreads - not found
-- Looking for pthread_create in pthread
-- Looking for pthread_create in pthread - found

As you can see, the cmake try to test the C compile features, but it failed.

How we integrate qrintf with cmake?
