[CMake] Cross compile for ADSP SHARC using the CrossCore toolchain

Hi,

I am trying extend my CMake toolchain of a C project, to be able to
cross compile for an Analog Devices SHARC DSP, specifically the SC589, 
which is a fairly new model.
This C project is split up into several modules, which should each be 
build as a separate library.

I saw that people seem to have successfully cross compile with CMake 
using the
CMakeADSP toolchain as described in the CMake wiki. This uses the 
VisualDSP++ suite from Analog Devices.
However, Analog Devices have released a new IDE/toolchain for developing 
on DSPs, which is called
CrossCore Embedded Studio.  And that is where I am struggling to make it 
work.

What I did was getting the Generic-ADSP-Common.cmake and the 
Generic-ADSP-C.cmake files. I modified them
to fit the new folder structure of CrossCore, which is slightly 
different to the VisualDSP++ one. So it can find
the correct DSP specific libraries etc.

Then I wrote a toolchain file adsp.cmake:

    SET( CMAKE_SYSTEM_NAME ADSP-C )

    SET( CMAKE_MAKE_PROGRAM "C:/Analog\ Devices/CrossCore\ Embedded\
    Studio\ 2.1.0/make.exe" )
    SET( CMAKE_GENERATOR "Unix Makefiles")

    SET( ADSP_PROCESSOR "ADSP-SC589" )
    SET( ADSP_PROCESSOR_SILICIUM_REVISION "none" )

    # specify the cross compiler
    SET( CMAKE_C_COMPILER "C:/Analog\ Devices/CrossCore\ Embedded
    Studio\ 2.1.0/cc21k.exe" )
    SET( CMAKE_CXX_COMPILER "C:/Analog\ Devices/CrossCore\ Embedded
    Studio\ 2.1.0/cc21k.exe" )
    SET( CMAKE_CXX_COMPILER_ARG1 "-c++" CACHE STRING "First argument" )
    SET( CMAKE_ASM_COMPILER "C:/Analog\ Devices/CrossCore\ Embedded\
    Studio\ 2.1.0/easm21k.exe" )
    SET( CMAKE_LINKER "C:/Analog\ Devices/CrossCore\ Embedded\ Studio\
    2.1.0/linker.exe" )

I am not sure, if this is actually even close to being correct. But it 
seems from the CMake build output, it actually does something remotely 
useful...
Then I invoke CMake via

     cmake -DCMAKE_TOOLCHAIN_FILE=../adsp.cmake -G "Unix Makefiles" ..

This is when I get a bunch of errors(see the bottom of the mail). From 
the errors, it seems that it wants to link against some 160_hdr.doj. I 
looked into the directory
in which all the libraries reside for my DSP and could not find it. Then 
I looked for libraries of the older DSPsand found out that only the ADSP 
21160 requires this library.
So I assume thatsomehow I could not manage to create a correct 
toolchain, because it still searches for the libraries of an older model?

Did anyone manage to cross compile using the new CrossCore toolchain and 
can give some info or can anyone elaborate on some steps I am quite 
possibly missing here?
Or will it not be possible to use the new ADSP CrossCore toolchain 
without performing in depth changes to the CMake code?

Thanks a lot in advance,
Merikan
