tl;dr of this thread (copied from http://www.reddit.com/r/FRC/comments...or_roborio_on/) Credit goes to u/ironmig

1. Install dependencies
   sudo apt-get install build-essential
   sudo apt-get install cmake
   sudo apt-get install gcc-arm-linux-gnueabi
   sudo apt-get install g++-arm-linux-gnueabi
2. Enter directory that will hold opencv
   cd ~/Documents
3. Clone OpenCV from git
   git clone https://github.com/Itseez/opencv.git
4. Checkout to a recent OpenCV release (change 2.4.10.1 to a recent release)
   cd opencv
   git checkout tags/2.4.10.1
5. Set toolchain to correct version of g++ (change line in file or run this complicated one-liner
   cd platforms/linux
   x=$(dpkg -s g++-arm-linux-gnueabi | grep "Version" | grep -o "..."); sed -i 's/set(GCC_COMPILER_VERSION "."/set(GCC_COMPILER_VERSION \"'$x'\" CACHE STRING "GCC Compiler version"/g' arm-gnueabi.toolchain.cmake
6. Prepare file for build
   mkdir build_roborio
   cd build_roborio
   cmake -DSOFTFP=ON -DCMAKE_TOOLCHAIN_FILE=../arm-gnueabi.toolchain.cmake ../../..
7. Build project (this will take a while)
   make

Disclaimer* I haven't actually tried this.
