使っていない機能のライブラリが足りない(not foundとなる)が、セキュリティーホールになるかも
しれないので適当に誤魔化した、誤魔化せてるのか？、の件、バットノウハウ。

libQt5OpenGL.so.5 => not found (Qtは入れない、使わない)
libQt5Network.so.5 => not found
libQt5Widgets.so.5 => not found
libQt5Network.so.5 => not found
libQt5Gui.so.5 => not found
libQt5Core.so.5 => not found
本来はQtのライブラリを誤魔化すのが最終目的だが、試しに他のライブラリで調べてやってみた。

Speech Dispatcher ライブラリが足りないため音声合成を使用できません

で入れたライブラリが依存するライブラリに不足があった。

libbaratinoo.so => not found、を誤魔化す。足りないのはオブジェクトではなく関数らしい。

うまくいけてそうなので、後は、/usr/local/libdummy とか作って、そこに libbaratinoo.so を入れて
/etc/ld.so.conf に登録するか。
とはいえ、外部にサービスを提供しているわけでもないし、数が多くてメンドクサいから当面やらない。

\-u とやるとリンクしてても使ってないライブラリを表示するらしい。含まれる全関数を使ってない?
$ ldd -u /usr/lib64/speech-dispatcher-modules/sd_baratinoo
