Auto2CMake

Auto2CMake is a pure python utility designed to simplify the process of migrating a project from Autotools or QMake to CMake 2.7 and above!

By automating the extraction and translation of build configurations, it reduces the manual effort required to modernize project build infrastructures.

Overview

It is often an incredible undertaking to go from Autotools' configure.ac and QMake's Makefile.am to a CMake CMakeLists.txt.

This project aims to streamline this process, allowing you to get right back into writing code, instead of worrying about reading hours of documentation.

Features

• Build System Translation: Handles the conversion of Autotools configuration logic into a CMake-compatible syntax.
• Target Management: Locates and defines binary build targets (both executables and libraries).
• Dependency Handling: Maps external dependencies and compiler flags to CMake's target-based configurations.

Requirements

• Python 3.9+
• This is the only requirement currently!

Building Auto2CMake

To compile Auto2CMake (auto2cmake.py) you can run the following commands:

Windows

    cd path/to/autocmake
    python bundle.py

Linux/MacOS

    cd path/to/autocmake
    python3 bundle.py

Usage

Once compiled, Auto2CMake offers two methods of usage.

Method 1: Drag and Drop (Easier)

• Originally Auto2CMake was developed to be dropped into the root directory of an Autotools/QMake project, alongside autotools.ac or Makefile.am.

  Windows

  python auto2cmake.py

  Linux/MacOS

  python3 auto2cmake.py

Method 2: Running with Arguments

• If you are dealing with a more complex workflow, or are trying to fully utilize Auto2CMake, then you will likely want to run the script with arguments.

  Windows

  python auto2cmake.py [OPTIONS]

  Linux/MacOS

  python3 auto2cmake.py [OPTIONS]

Options

Argument	Description
-h, --help	Displays more detailed information on supported commands.
-d, --directory=<dir>	Sets the working directory (defaults to current directory).
-e, --exclude=<dir1:dir2:etc>	Skips the provided directories during execution.
-c, --disable-comments	Prevents generation of comments in the CMakeLists.txt file.
-q, --quick	Enables Quick Mode (ignores Automake/QMake files, scans .cpp for QT).
-r, --recursive	Enables recursive directory walking.
-a, --automoc	Disables CMake Automoc and enables Qt source wrapping.
-v, --version=<version>	Pins the minimum CMake version (defaults to 2.8+).
