Compilation error when building browser

[DaVikingMan]

The following error is printed:
../src/frame/frame.c:35:62: error: ‘main_ui’ undeclared (first use in this function); did you mean ‘g_main_run’? 35 | builder = gtk_builder_new_from_string((const gchar *)main_ui, main_ui_len); | ^~~~~~~ | g_main_run ../src/frame/frame.c:35:62: note: each undeclared identifier is reported only once for each function it appears in ../src/frame/frame.c:35:71: error: ‘main_ui_len’ undeclared (first use in this function) 35 | builder = gtk_builder_new_from_string((const gchar *)main_ui, main_ui_len); |

Oh, it should build the ui file again (if missing). Starting with a freshly cloned repo and building that, should fix the issue.
Meson seems to be a bit buggy, when rebuilding multiple times from the same source. Removing the build folder or running ninja clean, might fix the issue.
