From the Developers Guide section on obtaining Qt, I've emboldened the important bits.

The main Wireshark application uses the Qt windowing toolkit. To install Qt, go to the “Download Qt” page, select “Go open source”, download the Qt Online Installer for Windows from the Qt Project and select, for the desired Qt version, a component that matches your target system and compiler. For example, at the time of this writing the Qt 5.15.2 “msvc2019 64-bit” component is used to build the official 64-bit packages.

Note that installation of separate Qt components are required for 32 bit and 64 bit builds, e.g. “msvc2019 32-bit” and “msvc2019 64-bit”. The environment variable QT5_BASE_DIR should be set as appropriate for your environment and should point to the Qt directory that contains the bin directory, e.g. C:\Qt\5.15.2\msvc2019_64

If you follow the instructions in the Developers guide, without deviation, you will end up with a working build system.
