[Bf-cycles] OSL branch and static libraries

[Thomas Dinges]

Hey Lukas,

I am on Ubuntu 12.04, x64 inside of VirtualBox.

Downloaded our RB-1.2 branch, llvm3.1 from llvm.org (Clang Binaries for 
Ubuntu-12.04/x86_64) and Blender trunk.
OSL compile itself was fine, I only had to give cmake LLVM_LIBRARY 
("libLLVMCore.a") manually.

Now Blender compile runs mostly smooth, but in the end I get an error:
[100%] [100%] make[3]: *** Keine Regel vorhanden, um das Target 
»/home/thomas/blender_dev/trunk/lib/linux64/llvm/lib/libLLVMIntelJITEvents.a«, 

   benötigt von »bin/blender«, zu erstellen.  Schluss.

I don't have an "libLLVMIntelJITEvents.a" though. Any ideas?

Regards,
Thomas
