[Interest] Static build of Qt - debug mode and plugins

[Jakub Narolewski]

Hello :]

I'm having a bit of a problem compiling my application in debug build mode under Linux.
Generally, under *nixes, I'm using self build, static Qt version. To configure Qt I'm using this simple one-liner:

// CONFIGURE START

// CONFIGURE END

Application compiles and runs fine - but only in Release mode.
As soon as I switch to debug versions of Qt and app I'm getting errors:

// ERRORS END

This looks like errors caused by missing Q_IMPORT_PLUGIN stuff on my side.
Which is funky, because on top of my main.cpp file I have:

#if defined(Q_OS_LINUX)
Q_IMPORT_PLUGIN(QPSQLDriverPlugin)
Q_IMPORT_PLUGIN(QSQLiteDriverPlugin)
#endif

And in my CMakeLists:

if (LINUX)
target_link_libraries(${TARGET_FULL_NAME}
    PRIVATE
		Qt5::QPSQLDriverPlugin
		Qt5::QSQLiteDriverPlugin
		"libpq.so"
)
endif()

I have tried removing "#if defined(Q_OS_LINUX)" in .cpp and my "if (LINUX)" check from CMakeLists but errors persists.
I’m currently using Qt 5.13.0

Any help will be appreciated,
Narolewski Jakub
