The point is that cmake is search the PATh variable and which is why it
is finding /usr/bin/pg_config instead of
/usr/lib/postgresql/9.1/bin/pg_config
The point of NO_DEFAULT_PATH argument is to prevent it from search the
default paths and to only look at the ones you are specifying.

The code below works on my system. I'm using cmake version 2.8.12.2
cmake --version
I don't know when that variable was added, you probably have an older
version. ALSO, rm -rf build/* so you clean out the cmake cache. It
didn't work until I cleared it.
