qt5base-lts/qmake/library/qmakeglobals.h
Oswald Buddenhagen 26d44fce3d introduce a new way to pass arbitrary arguments to the project file
this is done by recognizing the -- option and putting everything that
follows it into the QMAKE_EXTRA_ARGS variable.

the purpose of this is being able to pass "alien" arguments (for example
configure options) without having to marshal them into a qmake variable
assignment manually. this is expected to greatly enhance the convenience
when no wrapper script (i.e., configure itself) is used (which will be
the case outside qtbase).
