I try to compile but the linker is not happy, lots of undefine reference
to Qwt.
Qwt is compiled from CVS and src.pro is :

LIBS += -L/home/moa/sources/qwt/lib \
-ljack \
-lfftw3 \
-lsndfile
INCLUDEPATH += ../src \
/home/moa/sources/qwt/include \
/usr/include
MOC_DIR = ../moc
UI_DIR = ../ui
OBJECTS_DIR = ../obj
TARGET = ../bin/qloud
QT += xml
CONFIG += debug \
warn_on \
qt \
thread \
exceptions \
console
TEMPLATE = app

What do I miss?
