Add the Linaro toolchain bin directory to your PATH environment variable:
export PATH="/opt/gcc-linaro-arm-linux-gnueabihf-4.7-2013.01-20130125_linux/bin:$PATH"
or whichever directory you have extracted the Linaro HF tarball to.

Fernan, I'm using CMake 2.8.0. I have not tried to compile OpenCV with FFMPEG

Thank you very much Derek, some questions arises reading your response, e.g. How Cmake knows the PATH of arm-linux-gnueabihf-g++?
But now I will try to cross-compile again using your toolchain.cmake.
