What's the output of this command:

bin/llvm-config --libs "bitreader asmparser bitwriter instrumentation scalaropts ipo"

(executed from the root of your build directory)

Does it mention libLLVMCore ? From your command line it seems that CMake
was unable to determine the library dependencies. Either the
dependencies are wrong (hence the llvm-config check above) or the CMake
build is misinterpreting the output of llvm-config.

I don't know how well the LLVM cmake build worked for 2.5. In theory, it
should work the same way as for a unix host. In practice...
