Aha, so TeXmacs can be compiled with Qt5! Excellent (Qt4 will be removed 
from our distro (Gentoo) very soon). Unfortunately, when I configure with

--with-qt=/usr/lib64/qt5

compilation fails:

In file included from ./Plugins/Qt/QTMPrinterSettings.cpp:12:
./Plugins/Qt/QTMPrinterSettings.hpp:17:10: fatal error: 'QPrinter' file 
not found
#include <QPrinter>  // Provides QPrinter::PaperSize

The reason is: ./configure produces (see config.log)

QT_CXXFLAGS=' -isystem /usr/include/qt5 -isystem 
/usr/include/qt5/QtWidgets -isystem /usr/include/qt5/QtGui -isystem 
/usr/include/qt5/QtCore -isystem /usr/include/libdrm -pipe -O2 -Wall -W'

I.e., only QtWidgets, QtGui, and QtCore are here; but QtPrintSupport is 
absent. How should I patch configure.in so that configure also include 
QtPrintSupport to QT_CXXFLAGS (and to QT_LIBS? Does TeXmacs need it for 
linking? Now there is no QtPrintSupport in QT_LIBS).
