I added that, but I think it would be better to remove the error case.

In KDE we have a INSTALL_TARGETS_DEFAULT_ARGS variable, used like this:

 install(TARGETS klib1 ktool1 ${INSTALL_TARGETS_DEFAULT_ARGS})

Let's pretend the variable contains

 set(INSTALL_TARGETS_DEFAULT_ARGS  
   RUNTIME DESTINATION bin
   LIBRARY DESTINATION lib
   ARCHIVE DESTINATION lib
   INCLUDES DESTINATION include
 )

The problem is that all install(TARGETS) in KDE use the variable, but not 
all specify an EXPORT. EXPORT is not specified for utility (not usually 
executed directly by users) executables, kdeinit modules for example. 

So, I don't think it should be an error to specify INCLUDE DESTINATION 
without EXPORT. After all, I can specify LIBRARY DESTINATION for 
executables...

Thanks,

Steve.
