What do you mean by "generic rule" ?
An exemple would be welcomed.

What do you mean you check for ASPELL_FOUND even if you
don't need to use ASPELL?

Your CMakeLists.txt does not show the part where ASPELL is "discovered"
may be with something like
FindPackage(ASPELL).

I don't get your point. Dump where? In CMakeCache.txt?

Send the whole CMakeLists.txt and add comment where appropriate
I think it would be easier for us to understand what you want.
