Build failed when using wxgtk3 from the official repo

$ cmake --build .
..
[build] /usr/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/11.1.0/../../../../lib/libwx_gtk3u_webview-3.0.so: undefined reference to `webkit_web_view_go_back'

Build succeeded when using wxwidget that is built manually

$ cmake <folder_path_for_CMakeLists.txt> -DwxWidgets_CONFIG_EXECUTABLE=/opt/wxWidgets/bin/wx-config -DCMAKE_BULD_TYPE=Debug
$ cmake --build .

Have you checked the difference between the two generated Makefile/build.ninja files?

No
I have found the reason, after installing webkit2gtk in the official repo, it works.
I think it should be installed along with wxgtk3, right?

@Aragorn Nothing about AUR, why moved to AUR?

I’ve moved it to #support:applications now. But it either way has nothing to do with #support:programming.

I don’t know, is it a missing dependency in whatever you’re building? You never did say what it was.

It should be a missing dependency, by default it failed to link for the most basic usage of wxwidgets.
