Usage: $0 [-cdm] [-f <feature>]
    -c : clean dependencies instead of building
    -d : build DLL versions of dependencies (with exported symbols)
    -m : minimal build, with lots of features disabled and only
         built for the current platform instead of cross-compiling.
         Note that this disables many feature modules. You can re-enable
         them by specifying `-f <feature>' flags after `-m'.
    -f <feature> : enable building of feature. This can be used together
         with -m to enable minimal mode and then selectively only enable
         desired features. <feature> must be one of:
	"cairo" - enable building libcairo. Implies "png" and "freetype" below.
	"cglm" - enable building CGLM.
	"freetype" - enable building freetype.
	"geographic" - enable building GeographicLib.
	"glew" - enable building libGLEW.
	"jpeg" - enable building libjpeg.
	"lzma" - enable building LZMA.
	"openal" - enable building openal-soft.
	"opus" - enable building libopus and libogg.
	"png" - enable building libpng.
	"shape" - enable building libshp.
