CMake Swift Example

Example project which demonstrates CMake features used to build Swift code

What this is

This is an example project which demonstrates how to use the new Swift support in CMake to build a project using modern CMake techniques.

Why use this

CMake is a meta-build system that allows you to generate the build rules using different build tools. It also makes it possible to setup the build in a way which supports cross-compiling for various targets (including Linux, Windows, and android).

How to build this demo

If swiftc is not in your path, you will need to add -DCMAKE_Swift_COMPILER= with the path to swiftc.

cmake -G Ninja -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_TESTING=YES
cd build
ninja
ninja test

This invocation builds the project in release mode with debug information. This enables optimized builds with debug information. Additionally, the standard CMake option ENABLE_TESTING is used to enable tests. This builds tests and is used in the HelloWorldCore library to enable testable exports.

What is supported

This project builds on Linux, macOS, and Windows!

  • CMAKE_BUILD_TYPE

    • Debug (no optimizations, debug info)
    • Release (all optimizations, no debug info)
    • RelWithDebInfo (all optimizations, debug info)
    • MinSizeRel (optimized for size)

  • MSVC_RUNTIME_LIBRARY
