[digiKam-users] Error building digikam sources with ffmpeg 5

[Steven Robbins]

I'm attempting to build the head of Digikam git/master.  If I *disable* the 
video player (ENABLE_MEDIAPLAYER=false), the sources build successfully.

When the mediaplayer is ENABLED, I cannot configure; cmake displays

CMake Error at /usr/share/cmake-3.23/Modules/
FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find FFmpeg (missing: SWRESAMPLE_LIBRARIES
  SWRESAMPLE_INCLUDE_DIRS)
Call Stack (most recent call first):
  /usr/share/cmake-3.23/Modules/FindPackageHandleStandardArgs.cmake:594

  core/cmake/rules/RulesMediaPlayer.cmake:14 (find_package)
  core/CMakeLists.txt:112 (include)

Is this error familiar to anyone?  Any thoughts?

I'm using Debian linux (sid), with ffmpeg v 5.0.1 installed.  I believe I have 
all the Debian component packages.  For sure I have libswresample-dev:
