Qgroundcontrol building error (Window, QT 5.15.2)

[kent69]

I have installed Qt 5.15.2 from the source package on Windows to build QGroundControl, but when building QGroundControl, I encountered the following error. Can someone please help me? I have been trying to fix this error for 4 days, but haven't been able to resolve it.

Hi and welcome to devnet,

Do you mean you built Qt yourself ? If so, it looks like you did not enable OpenSSL support.

you need module network. Check if you installed network module.
