A quick C++ template for modern CMake projects, aimed to be an easy to use starting point.
This is my personal take on such a type of template, thus I might not use the best practices or you might disagree with how I do things. Any and all feedback is greatly appreciated!
Modern CMake configuration and project, which, to the best of my knowledge, uses the best practices,
An example of a Clang-Format config, inspired from the base Google model, with minor tweaks. This is aimed only as a starting point, as coding style is a subjective matter, everyone is free to either delete it (for the LLVM default) or supply their own alternative,
Static analyzers integration, with Clang-Tidy and Cppcheck, the former being the default option,
Doxygen support, through the
ENABLE_DOXYGEN option, which you can enable
if you wish to use it,
Unit testing support, through GoogleTest (with an option to enable GoogleMock) or Catch2,
Code coverage, enabled by using the
ENABLE_CODE_COVERAGE option, through
Codecov CI integration,
Package manager support, with Conan and Vcpkg, through their respective options
CI workflows for Windows, Linux and MacOS using GitHub Actions, making use of the caching features, to ensure minimum run time,
.md templates for: README, Contributing Guideliness, Issues and Pull Requests,
Permissive license to allow you to integrate it as easily as possible. The template is licensed under the Unlicense,
Options to build as a header-only library or executable, not just a static or shared library.
Ccache integration, for speeding up rebuild times
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.
This project is meant to be only a template, thus versions of the software used can be change to better suit the needs of the developer(s). If you wish to use the template as-is, meaning using the versions recommended here, then you will need:
CMake v3.15+ - found at https://cmake.org/
C++ Compiler - needs to support at least the C++17 standard, i.e. MSVC, GCC, Clang
Note: You also need to be able to provide CMake a supported generator.
If you wish to clone the repository, rather than generate from it, you simply need to run:
git clone https://github.com/filipdutescu/modern-cpp-template/
After finishing getting a copy of the project, with any of the methods above, create
a new folder in the
include/ folder, with the name of your project. Edit
cmake/SourcesAndHeaders.cmake to add your files.
You will also need to rename the
cmake/ProjectConfig.cmake.in file to start with
the exact name of your project. Such as
You should also make the same changes in the GitHub workflows provided, notably
.github/workflows/ubuntu.yml, in which you should
replace the CMake option
project( "Project" VERSION 0.1.0 LANGUAGES CXX )
to the exact name of your project, i.e. using the previous name it will become:
project( MyNewProject VERSION 0.1.0 LANGUAGES CXX )
To install an already built project, you need to run the
install target with CMake.
cmake --build build --target install --config Release # a more general syntax for that command is: cmake --build <build_directory> --target install --config <desired_config>
To build the project, all you need to do, after correctly installing the project, is run a similar CMake routine to the the one below:
mkdir build/ && cd build/ cmake .. -DCMAKE_INSTALL_PREFIX=/absolute/path/to/custom/install/directory cmake --build . --target install
Note: The custom
CMAKE_INSTALL_PREFIXcan be omitted if you wish to install in the default install location.
More options that you can set for the project can be found in the
cmake/StandardSettings.cmake file. For certain
options additional configuration may be needed in their respective
(i.e. Conan needs the
CONAN_REQUIRES and might need the
CONAN_OPTIONS to be setup
for it work correctly; the two are set in the
In order to generate documentation for the project, you need to configure the build to use Doxygen. This is easily done, by modifying the workflow shown above as follows:
mkdir build/ && cd build/ cmake .. -D<project_name>_ENABLE_DOXYGEN=1 -DCMAKE_INSTALL_PREFIX=/absolute/path/to/custom/install/directory cmake --build . --target doxygen-docs
Note: This will generate a
docs/directory in the project's root directory.
By default, the template uses Google Test
for unit testing. Unit testing can be disabled in the options, by setting the
cmake/StandardSettings.cmake) to be false. To run
the tests, simply use CTest, from the build directory, passing the desire
configuration for which to run tests for. An example of this procedure is:
cd build # if not in the build directory already ctest -C Release # or `ctest -C Debug` or any other configuration you wish to test # you can also run tests with the `-VV` flag for a more verbose output (i.e. #GoogleTest output as well)
