Well, this obviously works since the FORCE options are there. Here is an 
simple example to demonstrate the problem without FORCE:

set(INCLUDE_INSTALL_DIR      "${CMAKE_INSTALL_PREFIX}/include"             
CACHE PATH "The subdirectory to the header prefix")
message(STATUS "include: ${INCLUDE_INSTALL_DIR}")

INCLUDE_INSTALL_DIR is set to the install prefix you specified on the first 
cmake run and is not updated if you change the install prefix with another 
cmake call or in ccmake. And that's what I'm seeing with the latest kdelibs 
as well.
