#  -- Try to find OpenTURNS
  #
  #  OpenTURNS is an Open source initiative to Treat Uncertainties,
  #  Risks’N Statistics in a structured industrial approach,
  #  available at http://www.openturns.org/
  #
  #  ---------------------------------------------------------------------
  #
  #  -- Library usage example :
  #
  #  find_package (OpenTURNS 0.13.1)
  #  if (OPENTURNS_FOUND)
  #    include_directories (${OPENTURNS_INCLUDE_DIRS})
  #    add_executable (foo foo.cpp)
  #    target_link_libraries (foo ${OPENTURNS_LIBRARIES})
  #  endif ()
  #
  #  -- Module usage example :
  #
  #  find_package (OpenTURNS 0.13 COMPONENTS Trapezoidal)
  #  if (OPENTURNS_TRAPEZOIDAL_FOUND)
  #    include_directories (${OPENTURNS_TRAPEZOIDAL_INCLUDE_DIRS})
  #    add_executable (foo foo.cpp)
  #    target_link_libraries (foo ${OPENTURNS_TRAPEZOIDAL_LIBRARIES})
  #  endif ()
  #
  #  -- Show some debug information :
  #
  #  set (OPENTURNS_DEBUG TRUE)
  #  find_package (OpenTURNS)
  #
  #  ---------------------------------------------------------------------
  #
  #  -- This module defines :
  #
  #  OPENTURNS_FOUND - OpenTURNS is usable as a library
  #  OPENTURNS_INCLUDE_DIR - Where to find OT.hxx (not for general use)
  #  OPENTURNS_INCLUDE_DIRS - dependencies include directories
  #  OPENTURNS_SWIG_INCLUDE_DIR - Include directory to swig (.i) interface
  #  OPENTURNS_VERSION - Version string
  #  OPENTURNS_LIBRARY - Path to libOT.so (not for general use)
  #  OPENTURNS_LIBRARIES - Link these to use the library
  #  OPENTURNS_ROOT_DIR - Installation directory
  #  OPENTURNS_EXAMPLES_DIR - path to examples programs
  #
  #  OPENTURNS_WRAPPER_FOUND - OpenTURNS wrapper library is usable
  #  OPENTURNS_WRAPPER_DIR - Wrapper directory
  #  OPENTURNS_WRAPPER_LIBRARIES - Link these to use the wrapper
  #  OPENTURNS_WRAPPER_DEFINITIONS - Compiler switches required for wrapper
  #
  #  OPENTURNS_MODULE_DIR - OpenTURNS module directory
  #  OPENTURNS_MODULE_DEFINITIONS - Compiler switches required for module
  #  OPENTURNS_NAME_FOUND - True if module NAME was found
  #  OPENTURNS_NAME_INCLUDE_DIR - Module NAME headers
  #  OPENTURNS_NAME_INCLUDE_DIRS - Module NAME includes
  #  OPENTURNS_NAME_SWIG_INCLUDE_DIR - Module NAME swig (.i) headers
  #  OPENTURNS_NAME_LIBRARY - Module NAME library location
  #  OPENTURNS_NAME_LIBRARIES - Module NAME libraries location
  #  Macro add_module_extra_definitions(MODULE_NAME VERSION)
  #  MUST be called when building a module
