This commit:

produces this error:

CMake Error at CMakeLists.txt:13 (WRAP_LIBRARY): Unknown CMake command "WRAP_LIBRARY". CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: PYTHON_NUMARRAY_INCLUDE_DIR used as include directory in directory /media/USB-WD-1/dev-ubuntu/itk/WrapITK/ExternalProjects/PyBuffer

As ${NUMPY_PATH} is not set, the hard coded

/usr/share/pyshared/numpy/core/include/numpy/

path is the default on linux, but it seems it's not that standard.

Perhaps more important than automatically detecting the header file is to prompt the user about the choice between numerric and numpy as they are different libraries with different performances.

It may not be easy to automate numpy header detection,

numpy.get_include() is the standard method to find numpy headers. Perhaps your problem comes from the non detected WrapITK dir?

Also, numeric and numarray are both older libraries which should be replaced by numpy. I don't think we should care about choosing one or the other.

You're right, wrapitk dir was not found and it didn't warn me about it. Now numpy include path is well detected!
