[gentoo-user] Wireshark compile issue

[Anthony Delannoy]

Hi,

Release of wireshark 3.4.4 showed me an issue with my system.  Compilation,
linking & installation are OK with USE=-qt5, but when I try to install it with
qt5 flag I get a lot of undefined reference on qt5 symbols.

Extract of linking flags:
```
run/wireshark  -Wl,-rpath,"\$ORIGIN:"  run/libui.a  run/libcapchild.a  run/libcaputils.a  run/libwireshark.so.14.0.4  /usr/lib64/libQt5Multimedia.so.5.15.2  /usr/lib64/libQt5PrintSupport.so.5.15.2  /usr/lib64/libQt5Widgets.so.5.15.2  -lz  /usr/lib64/libspeexdsp.so  /usr/lib64/libminizip.so  /usr/lib64/libnl-genl-3.so  /usr/lib64/libnl-route-3.so  /usr/lib64/libnl-3.so  /usr/lib64/libpcap.so  run/libwiretap.so.11.0.4  run/libwsutil.so.12.0.0  -ldl  /usr/lib64/libgmodule-2.0.so  /usr/lib64/libgcrypt.so  /usr/lib64/libgpg-error.so  /usr/lib64/libgnutls.so  -lm  /usr/lib64/libglib-2.0.so  /usr/lib64/libQt5Network.so.5.15.2  /usr/lib64/libQt5Gui.so.5.15.2  /usr/lib64/libQt5Core.so.5.15.2
```

All of those libs are present and "works" well with my others qt5 packages, but
with wireshark (sample of errors):

```
...

```

I also tried wireshark-3.4.3 again and I have now the same issues.

Someone is experiencing the same ?

Have a nice day
