Synopsis
	Build projects.

Options
	-p, --platform {platform}
		Specify target platform.
	-c, --clean, --dontask
		Cleanup before building.
	-C, --cleanonly
		Cleanup only and exit.
	-j, --jobs {num}
		Specify how many jobs to build in parallel. Default is numb of CPUs.
	-J	Disable parallel build.
	-S	Disable silent make.
	--parallel {N}
		parallel build projects with N parallel job.
	-x {level}
		Build all dependant projects. Can specify level of dependency.
		Expand project dependency list, and build them in turn.
		Cannot be used with -r and default value is 0.
		For example, -x3 means to traverse dependency to 3rd level (itself as level 0)
	-r {level}
		Expand project dependency list reversely, then build all depending projects.
	-d, --with-debug
		Build with debugging definition.
	-N, --noclean
		Do not cleanup before building.
	--no-builtin
		Do not skip built-in projects.
	--with-ccache {size}
		Set size of ccache to reduce compiler activities. Default is $DefaultCCacheSize.
	--with-clean-ccache
		Build with a cleared ccache.
	--min-sdk {version}
		Specify minimum required SDK version (for example, 4.0).
	-h, --help
		This help message.
