QtPDF: configuration with -static-runtime causes linker errors for projects

If Qt is configured with -static -static-runtime and QtPDF is built using it, while QtPDF build itself succeeds without any problems whatsoever, building other projects fails with a long list of linker errors:

Qt5Pdf.lib(fpdf_doc.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MT_StaticRelease' in main.obj

Note: The error can be reproduced by trying to build the widgets pdfviewer example
