[CMake] What to cache and what not

[Andreas Pakulat]

Hi,

I'm a bit confused from readme.txt in the Modules directory, regarding
which variables in a FindFoo.cmake or in my case FooConfig.cmake should
be cached.

I'm going to provide a Foo_INCLUDE_DIR and a couple of Foo_LIBX_LIBRARY
variables and I'm wondering wether I should cache both or not?

Andreas
