As for Qt includes: What has cmake to do with include path of kdev4 ide?
Maybe I am missing some important part. is this path not given by some
environmental variable?

as for project includes: (includes from different projects)
what should be proper way to tell the IDE where are include files from some
different project located?

thanks
