There is an open wishlist bug [1] about properly mapping Debian 
architectures to CMake systems and processors.

A possible alternative would be the CMAKE_LIBRARY_ARCHITECTURE variable, 
which is initialized during compiler configuration for C, CXX, and 
Fortran and has the same value as DEB_HOST_MULTIARCH. Any 
architecture-specific setup in upstream code could be patched to check 
that variable instead of CMAKE_SYSTEM_PROCESSOR.


Cheers
Timo
