FindMaya
--------

This module finds the Maya SDK installation and provides variables
and functions for building Maya plugins.

Imported Targets
^^^^^^^^^^^^^^^^

This module does not define any library targets.

Result Variables
^^^^^^^^^^^^^^^

This module defines the following variables:

::

  MAYA_FOUND             - True if Maya SDK was found
  MAYA_INCLUDE_DIR      - Maya include directories
  MAYA_LIBRARIES        - Maya libraries to link against
  MAYA_VERSION          - The version of Maya found (e.g., 2023)
  MAYA_LOCATION         - The root Maya installation directory
  MAYA_BIN_DIR          - Maya bin directory
  MAYA_LIB_DIR          - Maya lib directory
  MAYA_PLUGINS_DIR      - Maya plugins directory

Hints
^^^^^

The user may set the following variables to help this module find what
they want:

::

  MAYA_VERSION          - Specify a specific Maya version to search for
                         (e.g., 2022, 2023, 2024, 2025, 2026)
  MAYA_LOCATION         - Specify the root Maya installation directory
                         (e.g., C:/Program Files/Autodesk/Maya2023)
