automoc cross compile uses paranoid path -I/use/include
For cross compiled Qt based application. Automoc moc_predefs.h generation process uses /use/include as include path. Whereas in case of cross this has to be from sysroot directory. In buildroot build options--advanced--paranoid unsafe path options is default set. By unseting this option I can build successfully. I have recently updated my fedora cmake 3.12.1 to 3.14.0. it is my first time I am reporting a bug on open source project. Hope this is the correct way and place to do the same.
