Should Qt .dlls be copied on build?

[BrodyHiggerson]

Hey there!

Thought I'd make a separate issue for my .dll issue.

I used the following to generate a solution:
C:\_Development\Projects\easy_profiler-develop\build>cmake -DCMAKE_PREFIX_PATH="C:\Qt\5.11.1\msvc2017_64\lib\cmake" .. -G "Visual Studio 15 2017 Win64"

When I build and run profiler_gui in Debug, it complains about missing .dlls, and in Release/RelWithDebInfo I get this error:

Both issues are fixed when I manually copy the Qt .dll files across. Should this not be happening automatically? I see no mention of this step in the install instructions for Windows.

Thanks!

Really it is not enough to copy the Qt libraries only. Sometimes you need also copy the C and C++ runtime libraries. So for me I use the next instruction, from Qt:
