CMake build instructions

Recommended usage : Incorporating cpu_features into a CMake project

For API / ABI compatibility reasons, it is recommended to build and use cpu_features in a subdirectory of your project or as an embedded dependency.

This is similar to the recommended usage of the googletest framework ( https://github.com/google/googletest/blob/main/googletest/README.md )

Build and use step-by-step

1- Download cpu_features and copy it in a sub-directory in your project. or add cpu_features as a git-submodule in your project

2- You can then use the cmake command add_subdirectory() to include cpu_features directly and use the cpu_features target in your project.

3- Add the cpu_features target to the target_link_libraries() section of your executable or of your library.

Disabling tests

CMake default options for cpu_features is Release built type with tests enabled. To disable testing set cmake BUILD_TESTING variable to OFF. e.g.

cmake -S. -Bbuild -DBUILD_TESTING=OFF
