Comment # 15 on bug 1140595 from Giacomo Comes

Installing on Leap 15.2 from network:telephony OBS repository:
as reported in comment 14, linphone starts but sort of hangs before opening any
window. I figured out that there is a dependency which is not installed and
makes linphone not start properly: if you install libsoci_sqlite3-4_0 then
linphone works. I think such missing dependency should go in the rpm liblime0.

There is another issue: when started from a terminal, linphone shows this
message:
  QML debugging is enabled. Use only this in a safe environment.

Such message can be eliminated by adding this line in linphoneqt.spec:

 %cmake \
   -DLINPHONE_OUTPUT_DIR="$PWD" \
   -DENABLE_UPDATE_CHECK=OFF \
+  -DCMAKE_BUILD_TYPE=Release \
   -DENABLE_STRICT=OFF       \
   -DENABLE_STATIC=OFF

linphoneqt could be upgraded to 4.2.2 as well.
