I am compiling a dependency for a project on Ubuntu 10.10, and instead of having it install to /usr/local by default, I am instead installing it to /tmp/stage/usr/local. How do I go about informing CMake of the location of this custom installed dependency when I call it to generate the build files for said project.
I am running CMake 2.8.1, and I have tried to set CMAKE_PREFIX_PATH on the cmake command line, like so
cmake -D CMAKE_PREFIX_PATH=/tmp/stage/usr/local
but this doesn't seem to make a difference - the project doesn't seem to detect the dependency.
Also, if it matters, the project in question is OpenCV 2.2, and the dependency in question is FFMPEG...
