I'm by no means a cross-compiling expert, but from what I know, you have
to provide a toolchain-file specifying the root directory containing the
toolchain (compilers, headers, libraries etc.), the target system name,
etc. The CMake WIKI [1] should be able to help you further. For Android
there's a project trying to build a common set of scripts and utilities [2].
