The MITK Utilities directory contains the source code of a couple of "external" projects. These should be removed from the utilities directory and added as proper external projects, just like ITK, VTK, etc.
Candidates are:
ann
glew
KWStyle (?)
Poco
qwt
qxt
tinyxml
This will reduce the size of the MITK sources, make it possible to set custom builds of these projects, and ease the creation of a future MITK SDK.
