# DEBUG=true
#  Building in debug mode
#  Implies SKIP_STRIPPING=true as well

# NOOPT=true
#  Do not automatically set optimization flags

# SKIP_STRIPPING=true
#  Do not strip output binaries

# NVG_DISABLE_SKIPPING_WHITESPACE=true
#  Tweak `nvgTextBreakLines` to allow space characters
#  FIXME proper details

# STATIC_BUILD=true
#  Tweak build to be able to generate fully static builds (e.g. skip use of libdl)
#  Experimental, use only if you know what you are doing

# FORCE_NATIVE_AUDIO_FALLBACK=true
#  Do not use JACK for the standalone, only native audio
