They assume you've already run CMake, since that's what's used to
build all of LLVM & Clang.

Similarly, they assume you've run CMake in a "normal" manner, as none
of the CMakeLists.txt files are self-contained. Eventually they're all
relative to llvm's top-level file.

Yes, examples don't get installed normally since they're not for
end-user consumption. However, you are very close; if you've built
Clang you should have a "PrintFunctionNames" target for make (i.e. you
can run "make PrintFunctionNames"). For me that creates
lib/PrintFunctionNames.so in the build directory.
