This directory contains CMake examples that demonstrate how to use Metall library from another CMake project.
If Metall is already installed on the system, one can use the find_package approach to locate and link it. Metall can be installed either by using a package manager or by building it from source using the CMake build system.
To have CMake download, install, and link Metall, see FetchContent.
In this case, Metall expects that required dependencies, such as Boost, are either already installed on the system or are provided through the FetchContent mechanism.
The Metall::Metall target carries Boost's usage requirements to consumers.
With JUST_INSTALL_METALL_HEADER, Boost setup is skipped; consumers must
provide and link Boost themselves. See the
header-only FetchContent example.
This approach allows users to manage Boost manually while still using Metall's CMake integration.
