[cmake-developers] target_include_directories branch in stage

[Alexander Neundorf]

...a somewhat related idea: if it will be possible to set include 
directories per target, and since it is already possible to set compile flags 
per target, it would be nice if I could also set a property on targets which 
keeps them from using the global settings at all.

Something like
set_target_properties(hello PROPERTIES COMPILE_FLAGS "..."
                                       INCLUDE_DIRS "..."
                                       IGNORE_GLOBAL_SETTINGS TRUE)

which would have the effect that neither the include directories for the 
current directory nor the global CMAKE_(C|CXX)_FLAGS would be used, but only 
what has been explicitely set for this target.

Sounds like a useful idea ?
If you think it makes sense, I might have some time to work on it.
