@Elvis Stansvik
That made CMake talk, thanks!

@Thiago Macieira
That was it, thank you very much :]

What confused me was that the program compiled fine in the release mode.
I made sure that CMake outputted makefiles related stuff and I then compared linking steps between modes:

/usr/local/Qt-5.13.0/lib/libqtpcre2.a -ldl -lssl -lcrypto 

In both cases I see that /usr/local/Qt-5.13.0/lib/libQt5Sql.a is listed before SQL plugins: libqsqlite.a and libqsqlpsql.a
Nevertheless, when I changed the order of plugins and Qt's Sql component application started building properly in Debug mode.

Thank you!

Jakub, to do this you can pass -DCMAKE_VERBOSE_MAKEFILE:BOOL=TRUE to CMake.
