[Insight-users] Wrong include path to GDCM in installed itk-3.0 version?

[Max Schoebinger]

Hi Mathieu,

thank you for taking the time looking into the problem. I checked your
example, and could reproduce my problem with it. I suppose that your
build and original itk-source tree are still accessible. Here is what
you need to do to reproduce the problem:

1. copy an itk source tree to /tmp/InsightToolkit-3.0.0
2. create a directory /tmp/itk-3.0-build
3. configure the build in the directory /tmp/itk-3.0-build using cmake 2.4.4
4. set CMAKE_INSTALL_PREFIX to /opt/itk-3.0
5. build itk in the directory /tmp/itk-3.0-build
6. make install

Now compile your example. It works fine... Lets continue by removing the
temporary source and build directories:

1. mv /tmp/itk-3.0-build /tmp/itk-3.0-build-moved
2. mv /tmp/InsightToolkit-3.0.0 /tmp/InsightToolkit-3.0.0-moved

Now try to compile your example again. It won't work (at least in my
configuration). The file /opt/itk-3.0/lib/InsightToolkit/ITKConfig.cmake
contains wrong values in the variable ITK_INCLUDE_DIRS:

max at muck:~> grep gdcm /opt/itk-3.0/lib/InsightToolkit/ITKConfig.cmake
SET(ITK_INCLUDE_DIRS
"/opt/itk-3.0/include/InsightToolkit;/opt/itk-3.0/include/InsightToolkit/Algorithms;/opt/itk-3.0/include/InsightToolkit/BasicFilters;/opt/itk-3.0/include/InsightToolkit/Common;/opt/itk-3.0/include/InsightToolkit/expat;/opt/itk-3.0/include/InsightToolkit/Numerics;/opt/itk-3.0/include/InsightToolkit/IO;/opt/itk-3.0/include/InsightToolkit/Numerics/FEM;/opt/itk-3.0/include/InsightToolkit/Numerics/Statistics;/opt/itk-3.0/include/InsightToolkit/Numerics/NeuralNetworks;/opt/itk-3.0/include/InsightToolkit/SpatialObject;/opt/itk-3.0/include/InsightToolkit/Utilities/MetaIO;/opt/itk-3.0/include/InsightToolkit/Utilities/NrrdIO;/opt/itk-3.0/include/InsightToolkit/Utilities/DICOMParser;/opt/itk-3.0/include/InsightToolkit/Utilities;/opt/itk-3.0/include/InsightToolkit/Utilities/vxl/vcl;/opt/itk-3.0/include/InsightToolkit/Utilities/vxl/core;/tmp/itk-3.0-build/Utilities/gdcm;/tmp/InsightToolkit-3.0.0/Utilities/gdcm/src")

As you can see, the paths relevant for gdcm usage point to the temporary
directories in /tmp

I am using SuSE Linux 10.1 on a 64 bit computer, cmake 2.4.4, gcc-4.1
and itk 3.0. I have attatched CMakeCache.txt for the itk build and the
corresponding cmake files from the lib/InsightToolkit directory.

I hope that my problem can be reproduced...
