[CMake] How to share CMakeCache between projects?

[Christoph Grüninger]

Hi CMake,
in our code we have different related CMake projects but CMake does not 
really know about dependencies between the projects. It would be handy 
to have only one CMakeCache.txt for all projects to reduce multiple 
execution of the Find*.cmake tests.
Is there a possibility to define the path to the cache file? Or is there 
another way to handle this?

Bye
Christoph
