Always compile the master document

[Yegor Yefremov]

Hello,

if I have master document with some child documents and I'm editing
the child and then invoke View->PDF(pdflatex) LyX tries to compile
only this child document and not the whole document beginning with
master. How can I change LyX behavior to always compile a whole
document regardless of what file is edited?

Regards.
