Done:

# It should be enough to only set CMAKE_C_COMPILER and CMAKE_CXX_COMPILER.

Yes, see here:
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0041c/Babbacdb.html
So I guess I can either use __arm or __ARMCC_VERSION
# The cmake compiler ID could then be named RVDS.

OK, so shall I make a local copy of Modules/CMakeCCompilerID.c.in and modify
that? I mean, would this copy take precedence if I add the local Module path
like this:
set(CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/../cmake/Modules
${CMAKE_MODULE_PATH})
# Thanks a lot :-)
And thanks to you for your support.
Cheers,
Abdel.

It doesn't work with the local copy unfortunately... but it works with the

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.

for this file.
It seems I can use a local copy of it as I got a warning about that (see
below). So I modified my local copy with the diff below but it doesn't work,
/usr/bin/ar is still used. One additional question: armar is apparently doing
the job of ar and ranlib so I don't want ranlib to be used afterwards so please
tell me how to avoid that.

Abdel.
