How to set the CMAKE_PREFIX_PATH?

I have a problem with the global environmental variable CMAKE_PREFIX_PATH. I already set this and I can see it is set when I type env, but when I run cmake . to build HipHop, it tells me that the variable isn't set.

Is there a way I can hard-code this into the makefiles?

Try to run cmake -DCMAKE_PREFIX_PATH=/your/path .

CMAKE_PREFIX_PATH works as a build directive, rather than as an environment variable. Moreover, you may perform the build into a dedicated temporary directory (it's cleaner, because when done, you can remove that temporary directory and you get back a clean pristine source tree).

$ mkdir -p tmpbuild && cd tmpbuild $ cmake -DCMAKE_PREFIX_PATH=~/deliveries/hiphop .. $ make install $ cd ..
