-Wl,-force_link flags not working correctly

If I link them like I was doing before cmake ensures that things are linked in the correct order. However, when I put them in quotes with the generator expression cmake no longer knows that these refer to the libraries

I guess that’s because you need both:

• target_link_libraries(utils_video_encode_decode_ffmpeg PUBLIC avfilter) for the “regular” dependency
• target_link_libraries(utils_video_encode_decode_ffmpeg PUBLIC "-Wl,-force_load $<TARGET_PROPERTY:avfilter,IMPORTED_LOCATION>") for the “force load”

Putting them together:

target_link_libraries(utils_video_encode_decode_ffmpeg
  PUBLIC
    avfilter
     "-Wl,-force_load $<TARGET_PROPERTY:avfilter,IMPORTED_LOCATION>"
)
