@Newsages I've been building for Boundary Devices Sabrelite board (MACHINE=nitrogen6x). I have not tried to build for the emulator.

Modifying the .pro file from the outside is not the correct idea. Since you only want to increment the build number you can mix both. VERSION from the pro file and build number generator that you can take inspiration from here

I had problems with adding an extra compile step. It was easier to use an extra make target. What I came up with was a .pro file like the following:

### BEGIN setup for CxxTest test program TEMPLATE = app TARGET = test_runner cxxtest.target = test_runner.cpp cxxtest.commands = $$PWD/../../../third_party/cxxtest/cxxtestgen.pl \ --error-printer --have-eh --have-std --abort-on-fail \ -o test_runner.cpp $$PWD/unit_test.h cxxtest.depends = $$PWD/unit_test.h QMAKE_EXTRA_TARGETS += cxxtest HEADERS += unit_test*.h SOURCES += $$OUT_PWD/test_runner.cpp INCLUDEPATH += $$PWD/../../../third_party/cxxtest DEPENDPATH += $$PWD/../../../third_party/cxxtest ### END setup for CxxTest test program ### library dependencies, including for code under test, go here
