[vtk-developers] question about PYTHON_LIBRARY dir. name

[Mathieu Malaterre]

Salut Donna,

  Please post VTK user question on vtk-users mailing, you'll easier
get much more answer this way, trust me.

  Even if your installation is a bit exotic, there is not need to
manually move lib around. In your case you did not enter the correct
information for cmake, you need to specify something like this:

         PYTHON_LIBRARY = /u2/donna/local/python/lib/python2.5/libpython2.5.so
         PYTHON_INCLUDE_PATH = /u2/donna/local/python/include/python2.5

the PYTHON_LIBRARY is supposed to be a filepath to the actual python
library, and not the directory containing the shared/static lib.

 For more info:

$ cmake --help-module FindPythonLibs

  will display what is actually done by cmake.
