New Revision: 275

Added:
   trunk/GREAT-ER-DB/cmake/FindPythonInterp.cmake
Log:
Add modified FindPythonInterp cmake file

In opposite to the original file this file searches first for the python executable
and if it's not found it tries to search for python27, python26, ... executables.
This allows to set the wanted python version in the environment. Cmake doesn't use
the newest version anylonger. Imho this is a much cleaner solution then before.

+#  PYTHON_EXECUTABLE          - path to the Python interpreter
+#  Python_ADDITIONAL_VERSIONS - list of additional Python versions to search for
