# TODO:
#   o Warning: CMake is forcing CMAKE_CXX_COMPILER to "/usr/lib/distcc/bin/g++" to
#     match that imported from VTK.  This is required because C++ projects must use
#     the same compiler.  If this message appears for more than one imported
#     project, you have conflicting C++ compilers and will have to re-build one of
#     those projects.
#     I get that type of warning when I use FEATURES="distcc" to emerge vtk
# Mini changelog:
#   o fixed symlinks in /usr/lib/python2.3/site-packages/vtk_python
#   o PATH, and VTK_DATA_ROOT problems not apparrent anymore
#   o java wrapping works now
#   o fixed some style changes according to ebuild guide
#   o FIXME: need to fix Examples/CMakeLists.txt to build other examples
#   o tcl/tk is actually required to compile, still using tcltk use flags for
#     enabling tcltk wrapping
#	o added mpi support
