[Cmake] Problems with LatestRelease

[Lorensen, William E (Research)]

I'm saying that something changed when I updated to LatestRelease yesterday.
Fred Wheeler pointed out a discussion of this a couple of emails back,

Are you saying that previously "${foo}" became "", and now "${foo}" is
left untouched when foo is not defined?  I'm pretty sure that the latter
has always been the case.  We are currently considering changing this
behavior to the former, though.

I just ran CMake on ITK with USE_FLTK set to ON, but no installation of
FLTK.  The CMakeCache.txt contains only NOTFOUND entries for these
libraries.  What is the actual problem you're having (or at least what
symptom are you seeing)?
