Is there a way to tell QMake to run a script after the build has finished?

Hello,

I want to run a deployment script after the build has finished, if the build was set to the RELEASE setting.
Is it possible to somehow tell QMake to run a script after it's done building?

Could you please elaborate? I don't quite understand what I should do.

Let's say I have a python script called myscript.py in the $PWD of the project. What do I need to do to run it after the build is finished?

I want to do something like

ONCE_BUILDING_FINISHED_RUN_COMMAND ( $$system(python "$${PWD}/myscript.py" SOME_ARG)

I admit that I don't quite understand how to do that from the link you provided.

Thank you for the link. I still fail to understand what I have to do.

add_custom_command(
        OUTPUT
            ${CMAKE_CURRENT_BINARY_DIR}/__header.h
            ${CMAKE_CURRENT_BINARY_DIR}/header.h
        DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/OriginalHeader.h
        COMMAND python ${py_cmd}
)

As far as I understand, the relevant command here is COMMAND python ${py_cmd} and what tells it to run is the custom target? Also, I'm using QMake, is it the same?

@Curtwagner1984 Sorry that is for cmake.

Maybe it's the same in QMake, the link @VRonin posted also has to do with adding a build target. Sadly I don't get exactly how to use it.

From what I understand, QMAKE_POST_LINK will run a script after linking. but not after building. (IE, before the .exe file is generated).

The other solution there involves making an extra build target with a dummy cpp file like so:

TEMPLATE = lib
SOURCES = placeholder.cpp # <== dummy cpp
CONFIG += no_link staticlib
batch_runner.target   = placeholder.cpp
batch_runner.commands = my_batch_file.bat # <== script to be run
QMAKE_EXTRA_TARGETS   = batch_runner

Is this the optimal solution?
