Probably my problem is simpler; that's my toolchain file for cross compile:
INCLUDE (CMakeForceCompiler)
CMAKE_FORCE_C_COMPILER   (gcc.exe GNU)
CMAKE_FORCE_CXX_COMPILER (gcc.exe GNU)


# this one is important
SET(CMAKE_SYSTEM_NAME Generic)
#this one not so much
SET(CMAKE_SYSTEM_VERSION 1)
#this one not so much
SET(CMAKE_SYSTEM_PROCESSOR MX1)

# specify the cross compiler
SET(CMAKE_C_COMPILER   "C:/Programmi/development/GCCARM/bin/gcc.exe")
SET(CMAKE_CXX_COMPILER "C:/Programmi/development/GCCARM/bin/gcc.exe")

# where is the target environment
SET(CMAKE_FIND_ROOT_PATH "C:/Programmi/development/GCCARM/bin")

# search for programs in the build host directories
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
# for libraries and headers in the target directories
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE NEVER)

I'd like, when I use this toolchian, the as.exe used in makefile is 
under C:/Programmi/development/GCCARM/bin (which is an ARM assembler) 
instead of in the environment variable %PATH% (which is a x86 assembler)
