CMake Template

A template for building C++ projects using modern CMake with dependencies handled by Conan.

Features

• Unit testing with CTest
• Conan integration for dependencies

Requirements

• C++17 compiler. Tested with
  • GNU GCC version 12,
  • LLVM Clang version 15
• CMake version 3.24 or above.
• conan version 2 (Recommended)

Dependencies

By default, the direct dependencies are:

• h5pp For fast and simple binary storage (includes hdf5, eigen, spdlog and fmt)
• Eigen3 For linear algebra
• fmt For string formatting
• spdlog For logging

These dependencies are installed automatically when using the bundled CMake Presets release-conan or debug-conan.

Note that h5pp itself has the same dependencies, so they should already be present if h5pp was installed previously.

Compatibility

This template has only been tested in Linux environments.

Usage with CMake Presets

Build as any regular out-of-source CMake project after installing the dependencies above.

Use the bundled CMake Presets to opt-in to automatic dependency installation with conan.

Step 1: Install conan

pip install conan
conan profile detect

Step 2: Clone CMakeTemplate and list its presets

Open a terminal and run

git clone https://github.com/DavidAce/CMakeTemplate.git
cd CMakeTemplate
cmake --list-presets
-------------------------------------------------------
>    Available configure presets:
>
>      "release-conan" - Release|conan package manager
>      "debug-conan"   - Debug|conan package manager

Step 3: Configure and build

Select a preset listed in the previous step, and run

cmake --preset=release-conan
cmake --build --preset=release-conan

These commands configure the project and builds the executable at ./build/release-conan/CMT
