I'm trying to install from source 5.2 on Ubuntu 17.04. At first I had this:

gnuplot wxterminal/wxt_gui.o: undefined reference to symbol 'XInitThreads'

Then I followed this:

http://knanagnostopoulos.blogspot.com/2016/02/ubuntu-1510-compiling-gnuplot-50-tweaks.html

But now I have 

qtterminal/qt_term.cpp:51:18: fatal error: QtCore: No such file or directory
 #include <QtCore>
                  ^
compilation terminated.
Makefile:916: recipe for target 'qtterminal/qt_term.o' failed
make[4]: *** [qtterminal/qt_term.o] Error 1
...

Any ideas what I need to do?
