Ok, now is attached what I actually wanted to attach.
If FORCE is used, then the "calculations" are done everytime and the results 
go into the cache.
This has the effect that if you set LIB_SUFFIX to something, it ends up in 
LIB_INSTALL_DIR, PLUGIN_INSTALL_DIR etc.
But it has also the effect that changing e.g. EXEC_INSTALL_PREFIX is not 
possible.
You can set it to /foo/bar/weirdo/ in ccmake, but after configuring it is set 
back to CMAKE_INSTALL_PREFIX -> due to the force. And since LIB_INSTALL_DIR, 
BIN_INSTALL_DIR etc. use EXEC_INSTALL_PREFIX, they are also set back to 
CMAKE_INSTALL_PREFIX because of the FORCE.

Without FORCE chaning LIB_SUFFIX in ccmake changes nothing, because the new 
value of LIB_SUFFIX isn't FORCEd into the other variables. 
But now you are able to edit all the install locations you want and set them 
as you want.
But if you run cmake the first time (i.e. with no CMakeCache.txt) like this:
cmake <dir> -DLIB_SUFFIX:STRING=64
then you get the behaviour you actually want.

Yet another option would be to use
SET(LIB_INSTALL_DIR ${EXEC_INSTALL_PREFIX}/lib${LIB_SUFFIX} )

Then you can edit LIB_SUFFIX and EXEC_INSTALL_PREFIX later on and 
LIB_INSTALL_DIR will reflect the changes (since now it doesn't come from the 
cache).
But in this case you are not able to change LIB_INSTALL_DIR to arbitrary 
locations (as it is possible with CACHE and no FORCE). I expect that then 
there will also be people which will complain.

So to make it short:
as it is now:
specifiy LIB_SUFFIX when running cmake the first time
after that edit every install location as you want 

Is that ok for you ?

Bye
Alex
