Introduction

This is an example of how to create a Modern CMake C++ Project.

This project should run on GNU/Linux, MacOS and Windows.

Requirement

You'll need:

• "CMake >= 3.16".

Codemap

The project layout is as follow:

• CMakeLists.txt Top-level for CMake based build.

• cmake Subsidiary CMake files.

• ci Root directory for continuous integration.

• Foo Root directory for Foo library.

  • CMakeLists.txt for Foo.
  • include public folder.
    • foo
      • Foo.hpp
  • src private folder.
    • src/Foo.cpp

• Bar Root directory for Bar library.

  • CMakeLists.txt for Bar.
  • include public folder.
    • bar
      • Bar.hpp
  • src private folder.
    • src/Bar.cpp

• FooBar Root directory for FooBar library.

  • CMakeLists.txt for FooBar.
  • include public folder.
    • foobar
      • FooBar.hpp
  • src private folder.
    • src/FooBar.cpp

• FooBarApp Root directory for FooBarApp executable.

  • CMakeLists.txt for FooBarApp.
  • src private folder.
    • src/main.cpp

Dependencies

To complexify a little, the CMake project is composed of three libraries (Foo, Bar and FooBar) with the following dependencies:

Foo:
Bar:
FooBar: PUBLIC Foo PRIVATE Bar
FooBarApp: PRIVATE FooBar

note: Since Foo is a public dependency of FooBar, then FooBarApp will see Foo inlude directories

Build

To build the C++ project, as usual:

cmake -S. -Bbuild -DCMAKE_BUILD_TYPE=Release
cmake --build build --config Release
