example build only in local folder

[snprrr]

I'm trying to build some examples. when i'm building in /usr/local everything works just fine and every example compiles. But if I try to build the examples in QT Creator or in another folder like Download Folder the example doesnt compile and is throwing errors like hell. For example:

scrollzoomer.cpp:68:25: Fehler: »class QwtPlotLayout« hat kein Element namens »setAlignCanvasToScale«
(class QwtPlotLayout has no element named setAlign....)

I tried alot of things but i dont get it to work. Has someone a hint? Im afraid that this question was asked before but i didnt find an answer that fits.

Greetings snprr

EDIT:

It seems like I can solve it by adding this stuff to the *.pro:

unix:!macx:!symbian: LIBS += -L$$PWD/../../../../../../usr/local/qwt-6.1.0/lib/ -lqwt
 
INCLUDEPATH += $$PWD/../../../../../../usr/local/qwt-6.1.0/include
DEPENDPATH += $$PWD/../../../../../../usr/local/qwt-6.1.0/include

unix:!macx:!symbian: LIBS += -L$$PWD/../../../../../../usr/local/qwt-6.1.0/lib/ -lqwt

INCLUDEPATH += $$PWD/../../../../../../usr/local/qwt-6.1.0/include
DEPENDPATH += $$PWD/../../../../../../usr/local/qwt-6.1.0/include

To copy to clipboard, switch view to plain text mode 

but is there any way to avoid that? I think "Config += qwt" is quite a lot easier
