CMake Examples

Introduction

CMake is a cross-platform open-source meta-build system which can build, test and package software. It can be used to support multiple native build environments including make, Apple’s xcode and Microsoft Visual Studio.

This repository includes some example CMake configurations which I have picked up when exploring it’s usage for various projects. The examples are laid out in a tutorial like format. The first examples are very basic and slowly increase in complexity drawing on previous examples to show more complex use cases.

These examples have been tested on Ubuntu 14.04 but should work under any Linux system that supports CMake.

This branch works with the CMake version 3.x onwards. For examples that use CMake version 2.x see the branch v2-style-includes.

Build Status

Requirements

The basic requirements for most examples are:

  • CMake v3.x

  • A c++ compiler (defaults to gcc)

  • make

Installation on Ubuntu

The easiest way to install the above on Ubuntu is as follows

$ sudo apt-get install build-essential
$ sudo apt-get install cmake

Some specific examples may require other tools including:

  • boost

    $ sudo apt-get libboost-all-dev

  • protobuf

    $ sudo apt-get install libprotobuf-dev
$ sudo apt-get install protobuf-compiler

  • cppcheck

    $ sudo apt-get install cppcheck

  • clang

    $ sudo apt-get install clang-3.6

  • ninja

    $ sudo apt-get install ninja-build

Docker

Docker containers with all requirements and various versions of CMake are generated to help make testing the examples easier. These are available from the docker hub repository matrim/cmake-examples.

To build the full set of cmake-examples test cases you can run:

docker run -it matrim/cmake-examples:3.4.3
git clone https://github.com/ttroy50/cmake-examples.git
cd cmake-examples
./test.sh

For more details on build and running the docker containers dockerfiles.

Other Links

There are many CMake tutorials and examples online. The list below includes links to some of these which I have found helpful in my CMake journey.
