For Linux or Windows? I remember that for windows you can add under qt creator the Maemo5 gcc with the package manager. The creator will load the packages from the remote repository,

package manager->QT SDK ->Development Tools->Maemo Toolchain

If you can not update the QT SDK, I can pack my qt sdk windows with harmattan, maemo and for both the quemu emulator. For Linux I need to look what I have installed if it is 64bit and if both toolchains are installed.
