CMake warning: Could NOT find LibBfd

[KivApple]

I use Cgreen inside my project using add_subdirectory to avoid necessity for user to install anything except CMake and C/C++ compiler to build my project. I get annoying warnings like

-- Could NOT find LibBfd (missing: LIBBFD_LIBRARY LIBIBERTY_LIBRARY LIBBFD_INCLUDE_DIRS) 
CMake Warning at lib/cgreen/tools/CMakeLists.txt:45 (message):
  libbfd not found, cgreen-runner will not be built

But missing of cgreen-runner is fine for me and expected behavior. Is it possible to add some option to explicitly disable building of cgreen-runner and get rid of this warning?

In 9cbc397ed62024f630b8bc2c338b03f7726aa8e4 I've added a CMake variable, CGREEN_BUILD_RUNNER, that actively selects/deselects building the auto-discovering runner.

I'm no CMake expert so I don't know if this will prevent trying to find libbfd, but it's a start.

Could you please try it?

[KivApple]

Yes, the warning has gone. Thank you!

Now I only have to make that official by documenting it.

Closing this as we will be reverting the use of libbfd as outlined in #302
