Cool, thanks.  I just started reading over that now.  I have a couple
of questions already, if you don't mind:

1) I see you're building the pass with

    add_library(lt-cc-static STATIC StaticCallCounter.cpp
DynamicCallCounter.cpp)
    add_library(lt-cc-shared MODULE StaticCallCounter.cpp
DynamicCallCounter.cpp)

  What's the reason for building a STATIC version?  Does any LLVM tool
  make use of that?

  Is add_library the preferred pass-building CMake macro these days,
  as opposed to add_llvm_library or add_llvm_loadable_module?

2) How is the user supposed to install the generated files?  Neither
   "make install" nor "cmake --target=install" seem to work.
