FWIW: I found why I use CMAKE_FORCE_C_COMPILER rather than the simpler
CMAKE_C_COMPILER command:
I build projects for eCos from outside the eCos tree directory, and
CMake has some trouble finding the eCos header files when simply using
CMAKE_C_COMPILER. It complains about CMAKE_FIND_ROOT_PATH which is
nevertheless defined as expected.

Cheers,
