Comment (by knarf):

 It is not necessary to require a particular capability in order to include
 _some_ header file.

 The Cactus-mechanism for header-files is more like 'I would like to
 include whatever other thorns provide under that header-name, if any.'
 This does not introduce a dependency of thorns.

 This is not what you want in your case. In your case you want one
 particular header file: that of thorn LoopControl. There should not be
 another thorn providing this file, and for sure not multiple. You have to
 have LoopControl to have that file, thus the required dependency.
