Yes, that's why I suggested to search the mailing list too. I wasn't
sure there's something in the knowledge base :(

Right...
During the build few helper tools are compiled and used in the build.
See http://www.cmake.org/Wiki/CMake_Cross_Compiling
In particular, we implement the solution from
http://www.cmake.org/Wiki/CMake_Cross_Compiling#Using_executables_in_the_build_created_during_the_build

So, you need to build for the native platform first. Not everything, just
"import_executables" target:

  make import_executables

This will create import_executables.cmake file. When you cross-compile
you'll need to set IMPORT_EXECUTABLES to the path to that file.
