 I'm using an Intel Macbook Pro (Retina 13-inch, Late 2013 edition) to
 homebrewing ffmpeg use custom configs as follow:

 {{{
 brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-libcaca --with-openjpeg
 --with-fdk-aac --HEAD
 }}}

 Under working environment of MacOS Big Sur 11.6.1 and Xcode command line
 tool version 13.2. Yet, it happened failure of ffmpeg installation with
 the log follows:

 {{{
 ==> make install
 Last 15 lines from /Users/tommy/Library/Logs/Homebrew/ffmpeg/02.make:

 Failed to execute metal libavfilter/metal/vf_yadif_videotoolbox.metal -o
 libavfilter/metal/vf_yadif_videotoolbox.metal.air

 Xcode and/or the CLT appear to be misconfigured. Try one or both of the
 following:
   xcodebuild -license
   sudo xcode-select --switch /path/to/Xcode.app

 make: *** [libavfilter/metal/vf_yadif_videotoolbox.metal.air] Error 1
 make: *** Waiting for unfinished jobs....
 }}}

 Just asked the GitHub contributors with the same question, but they all
 said there is a problem of compling "vf_yadif_videotoolbox.metal" file on
 Intel Mac (ARM Mac seems no such problem per contributor's quote). Is it a
 problem of compilation during the process? Hope there will be some
 answers, thank you.
