The attached patch implements the things we have discussed.  An appropriate commit message would be:

>>>
Improve optional capability requirement

* Introduce makefile and preprocessor variables HAVE_CAPABILITY_<cap> for each provided capability

* Remove incorrect definition line

* Rename cctki_Capabilities.h to cctk_Capabilities.h and exclude it from dependency checking (dependencies of the files included from this one will be sufficient)
