Fix -DCLANG_JLL=True mode of cmake

TODO list update

fixed test cmake build on macos

Bug fix: automatic wrapping of types used by functions was no more

effective for *global* functions.

- The bug was introduced by commit de83cd7 and release 1.1.0.
- Added unit test for this feature, TestAutoAdd.

Fix inconsistencies left after adding the support of relative resource

name in the macro names used to pass the default Clang resource directory
path from build configuarion (cmake).

minor change in makefiles to remove a warning with new julia releases

removed few uncessary statements from demo_fit_with_jl_func_2.jl
example.
