Cross-compiling:
42+
An example toolchain file for the CodeSourcery ARM toolchain is included in
43+
the cmake directory: codesourcery-arm-toolchain.cmake.
44+
45+
Install the CodeSourcery toolchain, set the path to the toolchain in
46+
cmake/codesourcery-arm-toolchain.cmake, and uncomment the TOOLCHAIN_FILE
47+
variable in Makefile.cmake to use it.
48+
49+
If you are using cmake directly, just add the flag
50+
"-DCMAKE_TOOLCHAIN_FILE=/path/to/toolchain-file" when
51+
running cmake.
