# Description
#     Setup file for VTK (and MESA)
#
#     The library path is only adjusted when the paths specified here
#     actually exist at the time of sourcing.
#
# Note
#     When _foamAddLib is unset
#       - vtk_version, mesa_version variables are retained.
#         (for future integration into ThirdParty build)
#
# It is recommended to use VTK sources from ParaView (5.0.1 or later).
# When doing so, the ParaView_MESA_DIR variable can be set accordingly.
#
# See doc/BuildIssues.md about problems that can be encountered when using
# the 'plain' VTK sources.
