[CMake] What does `cross-platform' mean?

[Bill Hoffman]

I have created a new wiki entry here:

http://www.cmake.org/Wiki/CMake:Improving_Find*_Modules#Proposed_solutions_to_Find.2A_issues

I merge the information in these entries into the above entry:
   http://www.cmake.org/Wiki/CMake:Static_libraries
   http://www.cmake.org/Wiki/CMake:Multiple_versions

Then remove the Static_libraries and Multiple_versions entries.   Some 
of the information is duplicated and some of it can be put in the 
current workaround section I created.   Jed can you take a pass at that?

Thanks.
