Template For C++ Projects

This is the final project of my Udemy Course. See here to get the full discount to all of my Udemy Courses: Link

This is a template for modern C++ projects. What you get is:

• Library, executable and test code separated in distinct folders
• Use of modern CMake for building and compiling
• External libraries installed and managed by
  • CPM Package Manager OR
  • Conan Package Manager OR
  • VCPKG Package Manager
• Unit testing using Catch2 v2
• General purpose libraries: JSON, spdlog, cxxopts and fmt
• Continuous integration testing with Github Actions and pre-commit
• Code documentation with Doxygen and Github Pages
• Tooling: Clang-Format, Cmake-Format, Clang-tidy, Sanitizers

Library code goes into src/, main program code in app/ and tests go in tests/.

Software Requirements

• CMake 3.21+
• GNU Makefile
• Doxygen
• Conan or VCPKG
• MSVC 2017 (or higher), G++9 (or higher), Clang++9 (or higher)
• Optional: Code Coverage (only on GNU|Clang): gcovr
• Optional: Makefile, Doxygen, Conan, VCPKG

Building

First, clone this repo and do the preliminary work:

git clone --recursive https://github.com/franneck94/CppProjectTemplate
mkdir build

• App Executable

cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build . --config Release --target main
cd app
./main

• Unit testing

cmake -H. -Bbuild -DCMAKE_BUILD_TYPE="Debug"
cmake --build build --config Debug
cd build
ctest .

• Documentation

cd build
cmake -DCMAKE_BUILD_TYPE=Debug ..
cmake --build . --config Debug --target docs

• Code Coverage (Unix only)

cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=Debug -DENABLE_COVERAGE=On
cmake --build build --config Debug --target coverage -j4
cd build
ctest .
