FFmpeg build not successfully about ffmpeg-gl-transition

[transitive-bullshit]

The error looks like glfw isn't being found. Make sure it's installed properly.

Mac OS should build fine as it's been thoroughly tested. Not sure about Android.

I'm having a similar issue in 'make' on High Sierra 10.13.5:

Undefined symbols for architecture x86_64:
  "_glfwCreateWindow", referenced from:
      _setup_gl in libavfilter.a(vf_gltransition.o)
  "_glfwDestroyWindow", referenced from:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [ffmpeg_g] Error 1

I know glfw is installed correctly.

🍺 /usr/local/Cellar/glfw/3.2.1: 14 files, 286.3KB

This is from the configure file:

385 --extra-ldsoflags=ELDFLAGS add ELDFLAGS to LDSOFLAGS [$LDSOFLAGS]
386 --extra-libs=ELIBS add ELIBS [$ELIBS]
387 --extra-libs='-lGLEW -lglfw'
388 --extra-version=STRING version string suffix []

I'm manually editing the file to insert the line --extra-libs='-lGLEW -lglfw'.

@NCPatrick
hi
please use --extra-libs='-lGLEW -lglfw'. when ./configure.
edit the configure file at that line only affect the output of ./configure --help
