I can confirm that some plugins still crash because of underlinking on
Ubuntu 16.04 with current CMake setup:

melt video.mp4 -attach frei0r.levels
crashes with:
melt: symbol lookup error: /usr/local/lib/frei0r-1/levels.so: undefined
symbol: pow

This is fixed by my proposal. Also, adding an "--as-needed" flag works for
me:

set (CMAKE_SHARED_LINKER_FLAGS "-Wl,--as-needed")


For the record, the issue was raised in april on this list:
