Now that qt_add_executable doesn't set the WIN32_EXECUTABLE and MACOSX_BUNDLE properties anymore, pro2cmake needs to look at the qmake example projects and generate appropriate set_target_properties calls. The relevant CONFIG entries to look at are windows, console, app_bundle and cmdline. CONFIG += windows implies 'subsystem windows' on Windows, which maps to WIN32_EXECUTABLE == TRUE. CONFIG += console implies 'subsystem console' on Windows, which maps to WIN32_EXECUTABLE == FALSE. Aka the opposite of CONFIG += windows. Whichever is the last one set, cancels out the other one. CONFIG += app_bundle implies a macOS bundle executable, which maps to MACOSX_BUNDLE == TRUE. CONFIG += cmdline is the same as CONFIG += console and CONFIG -= app_bundle, aka WIN32_EXECUTABLE and MACOSX_BUNDLE set to false. In qmake, if no CONFIG is specified in an example project, the default is CONFIG += windows app_bundle, aka WIN32_EXECUTABLE and MACOSX_BUNDLE set to true. The script uses a heuristic to try and not write the properties for every single subscope, except for values different from the default. This is not strictly correct, but it covers most use cases, and keeps the generated projects a bit cleaner.

CMake Utils
This directory holds scripts to help the porting process from qmake
to cmake
for Qt6.
Requirements
- Python 3.7,
pipenv
orpip
to manage the modules.
Python modules
Since Python has many ways of handling projects, you have a couple of options to install the dependencies of the scripts:
Using pipenv
The dependencies are specified on the Pipfile
, so you just need to run
pipenv install
and that will automatically create a virtual environment
that you can activate with a pipenv shell
.
Using pip
It's highly recommended to use a virtualenvironment
to avoid conflict with other packages that are already installed: pip install virtualenv
.
- Create an environment:
virtualenv env
, - Activate the environment:
source env/bin/activate
(on Windows:source env\Scripts\activate.bat
) - Install the requirements:
pip install -r requirements.txt
If the pip install
command above doesn't work, try:
python3.7 -m pip install -r requirements.txt
Contributing to the scripts
You can verify if the styling of a script complaint with PEP8, with a couple of exceptions:
Install flake8 (pip install flake8
) and run it
on the script you want to test:
flake8 <file>.py --ignore=E501,E266,W503
E501
: Line too long (82>79 characters),E266
: Too many leading '#' for block comment,W503
: Line break occurred before a binary operator)
You can also modify the file with an automatic formatter,
like black (pip install black
),
and execute it:
black -l 100 <file>.py
Using Qt's maximum line length, 100.
