I would like to propose the addition of a NO_CACHE keyword to the

Better wolution would be the equivalent of autoconf's './config.status
--recheck', e.g. reinvoking cmake with empty cache but with original
configuration options.
This is not what we want. We want to keep the cache variables since
the user might have changed it in the gui.
We just want some variables not to go into the cache (and hence not be
presented in the gui), but they automatically make it to the cache
because they are used in the find_xxx set of commands.
There is one more down side to NO_CACHE. It will mean that CMake will
look for these libraries every time it runs. If we did this with all
modules things would get pretty slow. I think what would be better is
some sort of dependent variable scheme and internal cache variables that
get cleared when the main variable changes. When wxWidgets_LIB_DIR
changes, then wxWidgets_core_LIBRARY should be looked up again. Also, I
assume that you do not want to allow the core library to be in a
different directory than wxWidgets_LIB_DIR which would be the other
effect. However, if you always know where wxWidgets_core_LIBRARY is
relative to wxWidgets_LIB_DIR, then why do you need to use find_library
to find it?
