It doesn't work with the local copy unfortunately... but it works with the modified installed version in /usr/share/cmake-2.8/Modules:

cmake ../src -Drvds=1 -Dfirmware=$2 -DCMAKE_TOOLCHAIN_FILE=../cmake/LinuxRvdsToolchain.cmake
-- The C compiler identification is RVDS
-- The CXX compiler identification is unknown

Compiling for ARM platform

I have used the __ARMCC_VERSION macro (see patch below).

So now I will try to remove CMAKE_(C|CXX)_CREATE_* and ARCHIVE variables and modify Modules/CMakeFindBinUtils.cmake; I hope I can use a local copy for this file.

Cheers,
Abdel.
