Joerg Bornemann 96bdcdacbc CMake: Implement configure -ltcg This configure switch sets the CMake variable CMAKE_INTERPROCEDURAL_OPTIMIZATION_<CONFIG> per release config to ON. The feature 'ltcg' is enabled if any of the variables CMAKE_INTERPROCEDURAL_OPTIMIZATION, CMAKE_INTERPROCEDURAL_OPTIMIZATION_<CONFIG> are ON. In order to implement the check, configurejson2cmake had to be extended to be able to write extra CMake code before and after the feature definition. This extra code can be added to a feature mapping below the keys "cmakePrelude" and "cmakeEpilogue".

CMake Utils

This directory holds scripts to help the porting process from qmake to cmake for Qt6.

Requirements

Python 3.7,
pipenv or pip 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.
