Thanks!  I've applied the first three:

 FindZLIB: Add imported target and documentation
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=5a7ff421

 FindGLEW: Add imported target and documentation
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=3d82a223

 FindX11: fix documentation formatting error
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=c90c7fca

I will respond to the individual patch messages for the other two.

That is not really supported anyway because we have only one
CMakeCache.txt so there is only one FOO_LIBRARY variable.
A project can achieve it with careful handling and typically
by keeping the find_package calls in separate directories
where imported targets are scoped apart anyway.
