# vtk_module(<name>)
#
# Main function for declaring a VTK module, usually in a module.cmake file in
# the module search path. The module name is the only required argument, all
# others are optional named arguments that will be outlined below. The following
# named options take one (or more) arguments, such as the names of dependent
# modules:
#  DEPENDS = Modules that will be publicly linked to this module
#  PRIVATE_DEPENDS = Modules that will be privately linked to this module
#  COMPILE_DEPENDS = Modules that are needed at compile time by this module
#  TEST_DEPENDS = Modules that are needed by this modules testing executables
#  DESCRIPTION = Free text description of the module
#  TCL_NAME = Alternative name for the TCL wrapping (cannot contain numbers)
#  IMPLEMENTS = Modules that this module implements, using the auto init feature
#  GROUPS = Module groups this module should be included in
#  TEST_LABELS = Add labels to the tests for the module
#
# The following options take no arguments:
#  EXCLUDE_FROM_ALL = Exclude this module from the build all modules flag
#  EXCLUDE_FROM_WRAPPING = Do not attempt to wrap this module in any language
#  EXCLUDE_FROM_WRAP_HIERARCHY = Do not attempt to process with wrap hierarchy
#
# This macro will ensure the module name is compliant, and set the appropriate
# module variables as declared in the module.cmake file.
