  --fatal-assert           make any call to assert abort program
  --strip                  enable strip
  --std-allocator          uses standard lib memory allocator
  --enable-sanitizer       enable address sanitizer
  --enable-afl             enable instrumentation for American Fuzzy Lop

  --disable-opt            disable GCC optimizations
  --static-build           link statically against libgpac but still allow dependencies to shared libraries (enable --static-modules)
  --static-bin             enable static linking of MP4Box and gpac only (will enable --static-build), disable all libraries not linkable statically.

  --em-size=V              total memory in bytes to use for emscripten - if 0, dynamic memory growth will be used [$em_size]

  --disable-x11            disable X11
  --disable-x11-shm        disable X11 shared memory support
  --disable-x11-xv         disable X11 Xvideo support
  --enable-depth           enables depth handling in the compositor (experimental for stereoscopic rendering)
  --disable-all            disables all features in libgpac (see below)
  --isomedia-only          disables all features except "parsers import export isom-dump isoff isoff-write isoff-hint isoff-frag isoff-hds ttxt ttml vtt mpd dash hevc"


Extra libraries configuration:
You can turn a library off or force using the local version in gpac/extra_lib/
  --use-FOO=no             disable library FOO
  --use-FOO=local          force use of library FOO in gpac/extra_lib/include, gpac/extra_lib/lib/gcc/bin/
  --use-FOO=system         force using system version only of library FOO
  --use-FOO=PATH           force use of library FOO in \$PATH/include, \$PATH/lib
