llvm dev - Aug 2013 - [LLVMdev] llvm cmake build option ((enable-experimental-targets=R600)) question

greetings 

I am new to this list.
 
I have recently  compiled llvm-3.3 from sources.  My machine has these:

--cpu -amd64
--os- clbfs 64bit  -linux3 series kernel
--C/C++ compiler -modern versions gcc


 My  preferred build tool is cmake.


llvm is needed for MesaLib and the autotools build of llvm allows this 
option:-
--enable-experimental-targets=R600
( for example described here:
http://www.linuxfromscratch.org/blfs/view/svn/general/llvm.html )

I have been unable to locate a equivalent option in the CMakeLists.txt in the 
base llvm-3.3 directory


I have also searched the llvm cmake documentation  here:-
http://llvm.org/releases/3.3/docs/CMake.html

to no avail.

The closest I have seen is this option 
-DLLVM_TARGETS_TO_BUILD

unfortuntely  the documentation does not elaborate if these targets include  
"experimental-targets=R600"  as per the autotools build.

So in a nutshell I would be grateful for some advice on how one enables this 
option in a cmake build of llvm-3.(2,3,4)

thanks in advance

R600 was added to the list of known targets on the top-level
CMakeLists.txt on June 22. So you can grab the LLVM development sources
from svn or git and it should work (TM).

If you wish to use LLVM 3.3, edit the top-level CMakeLists.txt file and
add R600 to the list of known targets (LLVM_ALL_TARGETS). Then build as
usual.

tried this and compilation progressed to  ~31% then  refused to go further
