cmake-common

Utilities to help develop C++/CMake projects.

Description

This main goal of this project is to make it easier to build (potentially, cross-compile) Boost and CMake projects using different toolsets. It does so providing a set of command-line utilities that allow users to download/build Boost & use it in a CMake project in a consistent way — no matter the compiler or the target platform.

Installation

• Via PyPI:

  pip install cmake-common
  

• As a submodule:

  git submodule add https://github.com/egor-tensin/cmake-common.git
  

  All the scripts provided by the PyPI package are thin wrappers around the project package modules:

  Script	Module
  boost-download	python3 -m project.boost.download
  boost-build	python3 -m project.boost.build
  project-build	python3 -m project.build

Toolsets

Supported platform/build system/compiler combinations include, but are not limited to:

1. Both GNU make and MinGW mingw32-make.
2. clang-cl is supported by Boost 1.69.0 or higher only.

All of those are verified continuously by the Boost (toolsets) and Examples (toolsets) workflows.

For a complete list of possible --toolset parameter values, pass the --help-toolsets flag to either boost-build or project-build.

Usage

Boost

Download & build the Boost libraries in a cross-platform way.

$ boost-download 1.72.0
...

$ boost-build -- boost_1_72_0/ --with-filesystem --with-program_options
...

Pass the --help flag to view detailed usage information.

CMake project

Build (and optionally, install) a CMake project.

$ project-build --configuration Release --install path/to/somewhere --boost path/to/boost -- examples/simple build/
...

$ ./path/to/somewhere/bin/foo
foo

Pass the --help flag to view detailed usage information.

common.cmake

Use in a project by putting

include(path/to/common.cmake)

in CMakeLists.txt.

This file aids in quick-and-dirty development by

• linking everything (including the runtime) statically by default,
• setting some useful compilation options (enables warnings, defines common Windows-specific macros, strips debug symbols in release builds, etc.).

Everything is enabled by default (use the CC_* CMake options to opt out).

Tools

• project-clang-format.py — clang-format all C/C++ files in the project.
• ctest-driver.py — wrap an executable for testing with CTest; cross-platform grep.

Examples

I use this in all of my C++/CMake projects, e.g. aes-tools and math-server.

Development

Make a git tag:

git tag "v$( python -m setuptools_scm --strip-dev )"

You can then review that the tag is fine and push w/ git push --tags.
