Ideally, I want to impose the following dependenc

Answer 1

I use the solution below. This works without the usage of an extra .pro file with subdir template.

TEMPLATE = app
TARGET = MyApp
PRE_TARGETDEPS = ../../libs/MyLib/MyLib.a
INCLUDEPATH += ../../libs/MyLib/include 
HEADERS += src/MyApp.h \
    ../../libs/MyLib/incude/MyLib.h
SOURCES += src/MyApp.cpp
LIBS += ../../libs/MyLib/MyLib.a

MyLib.target = ../../libs/MyLib/MyLib.a
MyLib.commands = cd ../../libs/MyLib && make
MyLib.depends = ../../libs/MyLib/Makefile
QMAKE_EXTRA_TARGETS += MyLib
