[CMake] (no subject)

Hi again :)

I have yet another question about something in cmake :)  For some
reason, variables seem to have different actions depending on where it
is used.  I'm trying to make a build system for our product and it seems
that dereferencing variables doesn't work in one place, but does in
another...

As far as ENV{} goes, sometimes it seems to need the $ENV{A}, sometimes
it uses the bare variable name ENV{A} and sometimes it needs the quotes
around them to work.  For example, STREQUAL sometimes doesn't work with
the quotes and sometimes does.  Can anyone give a clear description of
variable usage, including deferencing and such?  It's getting kind of
confusing..

Thanks!
