Build problems with custom pass living in its own directory (under Transforms)

I am having trouble integrating my custom pass into the build system such that it gets build along with the rest of the components and it's usable from code that links to LLVM.

My pass lives here:
ls -l lib/Transforms/qdp_jit/
LLVMBuild.txt Makefile qdp_jit.exports qdp_jit_roll.cpp
