Configuring CMake on macOS with cmake macos

When working with CMake on a variety of platforms, including AIX and Windows-based systems, it is essential to understand how the linker import file is created for executables. On all Windows-based systems, including Cygwin, the linker import file has an extension of `.dll`. However, when building a framework on macOS, the situation is slightly different.

In CMake, output artifacts can be specified by their kind, such as ARCHIVE. Additionally, output artifacts that do not have a dedicated group specified will use the default component name. This default component name can be controlled using the `MAKE_INSTALL_DEFAULT_COMPONENT_NAME` variable.

When installing a project, all components are installed unless they are marked with `EXCLUDE_FROM_ALL`. The given component name will be executed during installation. During component-specific installation, only install rules associated with the specified artifact kind are executed.

CMake also provides options for specifying build configurations and permissions for installation. For example, you can specify a list of permissions using arguments like `GROUP_WRITE`, `GROUP_EXECUTE`, `WORLD_READ`, etc. These permissions can be ignored on certain platforms that do not support them.

When generating installers with CMake, it is important to use relative paths throughout the configuration. This is because absolute paths are not supported by the cpack installer mechanism. The `CMAKE_INSTALL_PREFIX` variable is used as a prefix for all installation directories, and can be relocated at install time using the `DESTDIR` option.

Finally, CMake provides multiple signatures for the `install` command, which can be used to specify different installation options for files and targets. These signatures are explained in detail in the official CMake documentation.

In summary, configuring CMake on macOS requires a good understanding of how output artifacts are created, how components are installed, and how permissions are specified. By following these guidelines, you can successfully build and install your project using CMake.
