CMake can have multiple watches on a variable; how would you tell which
one to remove? I suppose a result variable could hold a token for it,
but then you have the problem of getting that variable passed around
(the cache defeating the purpose here; global properties not really
being the right thing either).

A bug report would be nice for this ;) .
