[cmake-developers] CMake build with static crt and static QtDialog not linking

[David Cole]

I had a project where I had to do this in the main.cpp file to get it
to link with static Qt on Windows:

    #ifdef _WIN32
    #ifdef QT_STATIC
    Q_IMPORT_PLUGIN(QWindowsIntegrationPlugin)
    #endif
    #endif

Those unresolved externals you posted look familiar... Does this fix it?


HTH,
David C.
