Various problems building hphp

[chrisgraham]

I had various problems building hphp, relating to the patched libraries. This is likely related to me building on the latest Kubuntu rather than Fedora.
The gist of all the problems was that the make system was finding includes and libraries from my main system's lib/include dirs rather than from the hiphop directory where I had compiled it all (I followed the Ubuntu instructions on the Wiki).
I ended up fudging it by copying the new ones over my system's ones.

I'm not sure if this is a problem with the Ubuntu build instructions, or a problem with how the make system is searching for dependencies.

If you set CMAKE_PREFIX_PATH to where it should search first, then clear CMakeCache.txt and try again it works.

In my case I use
export CMAKE_PREFIX_PATH=/home/macvicar/hiphop

in there I have lib + include folders
