Usage: cmake --build <dir> [options] [-- [native-options]]
Options:
<dir> = Project binary directory to be built.
--target <tgt> = Build <tgt> instead of default targets.
--config <cfg> = For multi-configuration tools, choose <cfg>.
--clean-first = Build target 'clean' first, then build.
(To clean only, use --target 'clean'.)
--use-stderr = Don't merge stdout/stderr.
-- = Pass remaining options to the native tool.
