Using a yocto/oe toolchain
--------------------------
In order to compile with a yocto/oe toolchain use the following toolchain file.
This works well on the edison 1.6 SDK. First source the environment file, then
use our cmake toolchain file.
~~~~~~~~~~~~~{.sh}
source /opt/poky-edison/1.6/environment-setup-core2-32-poky-linux
mkdir build
cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchains/oe-sdk_cross.cmake ..
make
