Subject: Error building EPICSQt

Hello, all

I'm trying to build the EPICSQt, using Ubuntu, but I have this problem, when I make directly on QT Creator:

-------
/usr/bin/ld: cannot find -lqwt
collect2: ld returned 1 exit status
-------

My epicsqt.pro file:

-------

   TEMPLATE = subdirs
   CONFIG   += ordered
   CONFIG   += qwt

message( Applications may need to load the framework library directly. To ensure this can happen one option is to set up LD_LIBRARY_PATH to include the directory <your-epicsqt-project-location>/framework/designer. LD_LIBRARY_PATH is currently $(LD_LIBRARY_PATH) )

message( Applications may need to load the framework library as a Qt plugin. To ensure this can happen one option is to set up QT_PLUGIN_PATH to include the directory <your-epicsqt-project-location>/framework. LD_LIBRARY_PATH is currently $(QT_PLUGIN_PATH) )

SUBDIRS = \
    framework \
    applications/QEGuiApp \
    applications/QEMonitorApp

-------

I have also other problem, resolved partly:

The EPICSQt does not find some libraries, like qwt_plot.h and qwt_plot_curve.h, that are in the folder "/usr/include/qwt-qt4/", and to resolve, I add the complete path in code. 

Example:

#include <qwt_plot.h>

Only works when I replace to:

#include </usr/include/qwt-qt4/qwt_plot.h>

I exported some enviroment variables:

QWT_INCLUDE_PATH = /usr/include/qwt-qt4/
EPICS_HOST_ARCH = linux-x86_64
EPICS_BASE = /home/ABTLUS/lucas.monteiro/Documentos/EPICS/base


Thanks in advance,
