Проблемы с libfontconfig / libxft-dev

У меня есть проблема с созданием LMMS.

Я добираюсь до этой точки:

Linking CXX executable RemoteZynAddSubFx
/usr/bin/ld: cannot find -lXft
/usr/bin/ld: cannot find -lfontconfig
collect2: error: ld returned 1 exit status
make[2]: *** [plugins/zynaddsubfx/RemoteZynAddSubFx] Error 1
make[1]: *** [plugins/zynaddsubfx/CMakeFiles/RemoteZynAddSubFx.dir/all] Error 2
make: *** [all] Error 2

Одно предложение состояло в том, чтобы установить libxft-dev, который я попробовал и следовал за процессом ниже:

Я довольно смущен. Справка очень ценилась бы!
