(WIP) CMake FetchContent example

This is WIP example of using CMake FetchContent in real world scenario. It downloads ImGui, SFML and ImGui-SFML and then a simple application uses these dependencies for building.

This example is interesting, because ImGui-SFML depends on both ImGui and SFML, so you can also see how fetched dependencies can work with each other is well.

Building is simple, just do:

mkdir build
cd build
cmake <path-to-cloned-repo>
cmake --build .
./src/imgui-sfml-example # or .\src\Debug\imgui-sfml-example.exe if you're on Windows

Options

You can also set the following options when building:

• USE_SYSTEM_DEPS (OFF by default) - search for SFML installed on system instead of fetching it
• LINK_DEPS_STATIC (ON by default) - link dependencies statically

Depencies

CMake >= 3.12

Also, if you're on Linux, you'll need to install dependencies for building SFML specified here.
