[Interest] How to deploy a qml app with Qt built statically?

[Nuno Santos]

Thiago,

After reading about it on:

http://doc.qt.io/qt-5/qtplugin.html

In .pro file I have added:

QTPLUGIN += qwindows

And in one of the source files I have added:

#include <QtPlugin>

Q_IMPORT_PLUGIN(qwindows)

And the result was:

error LNK2019: unresolved external symbol "struct QStaticPlugin const 
__cdecl qt_static_plugin_qwindows(void)" 
(?qt_static_plugin_qwindows@@YA?BUQStaticPlugin@@XZ) referenced in 
function "public: __thiscall 
StaticqwindowsPluginInstance::StaticqwindowsPluginInstance(void)" 
(??0StaticqwindowsPluginInstance@@QAE at XZ)

Sorry, but i'm lost here.

Regards,

Nuno
