[vtkusers] CMAKE + VTK + QT

[Francois Bertel]

Hello,

On Ubuntu 9.04, the only packages I installed are libqt4-dev and
libqt4-dev-dbg. Everything else have been installed by automatic
dependency solving.

Notably,

/usr/bin/qmake is a symlink to  /etc/alternatives/qmake
/etc/alternatives/qmake is a symlink to /usr/bin/qmake-qt4

/usr/bin/qmake-qt4 is provided by package "qt4-qmake" (automatically
installed with the dependency resolution above)

This command line checks which package provides /usr/bin/qmake-qt4:
$ dpkg -S /usr/bin/qmake-qt4
qt4-qmake: /usr/bin/qmake-qt4

Make sure that you /usr/bin/qmake is not a symlink pointing to an
non-existing file.
