Instead of +// asking the user to pass one of these options to the ODB compiler (which +// can, BTW, be done with -x -fPIE, for example, if one is not using the +// Qt profile), we are going to define __PIE__ ourselves just to silence +// Qt. We also want to try to minimize this to cases where it is actually +// necessary. To achieve this, we need to include the Qt config file without +// including <QtGlobals>, which is where the test for PIC/PIE is.
