How to know Shadow build directory in pro file?

[sevenjay]

How to know or set the shadow build directory path in pro file?
I have a execute binary and some libraries build in shadow build directory.
And I want to deploy it using INSTALLS in the pro file.
But I can't tell the build directory path.

@target.path = /usr/local/bin

lib.files += $$shadow_build_directory/lib/*
lib.path += /usr/lib

INSTALLS += target lib@

thanks

$$OUT_PWD is what you need I think.
