[Qtwebengine] Static builds of QtWebEngine aren't supported.

[Allan Sandfeld Jensen]

Mixed static and dynamic builds are not supported, but could technically be 
possible, but I have no idea how much work it would be.

You could try changing QtWebEngineCore into a lib TEMPLATE instead of a qt 
module, and set CONFIG += staticlib, that could at least make that statically
linked into the API libraries (at the cost of being duplicated).

You could probably also get away with making the qtwebchannel dependency 
optional (if you do, please contribute the patch).

Btw If you find any tricks that significantly reduces the library size, I 
would love to hear about them. It is not the first time the subject has come 
up.
