Add CMake project configuration

This patch adds a cmake configuration which allows to
cross-compile easily. A cmake variable named BUILD_DESTINATION
has been added to let the user choose to compile for target or
for host (enabled by default).
Just add -DBUILD_DESTINATION=TARGET when running cmake to
cross-compile.
