Support for the console pool should appear in cmake 3.2 (http://www.cmake.org/gitweb?p=cmake.git;a=commitdiff;h=444f61e0)  and our CMakeLists.txt's should be ready for it (http://llvm.org/viewvc/llvm-project?view=revision&revision=222181). I'm on cmake 3.0.2 so I haven't tried it for myself yet.

I'm afraid the sed approach is the only thing that I can think of.
