#===========================================================================
#
#    Description: Set up CMake environment variables pointing to Tulip components one can use to compile code using Tulip
#    Filename: FindTULIP.cmake
#    Authors: Tulip team
#
#===========================================================================
#
# The FindTULIP script can be used from any CMake-based project to set up environment variables poiting to Tulip libraries and headers directories.
# The FIND_PACKAGE command provides several arguments. While the COMPONENTS argument will be ignored, you can tell FindTULIP to look for a specific version of Tulip libraries:.
#
# FIND_PACKAGE(Tulip 3.5.0 REQUIRED) # Will look for Tulip 3.5.0 or higher
# See CMake documentation for details about the FIND_PACKAGE macro.
#
# By default, this script will try to automatically detect the installation directory of Tulip libraries installed on your system.
# You can override this behavior by defining the TULIP_DIR variable. If this variable is set, FindTulip will only check into that directory for a valid Tulip installation.
#
# This script will output the following variables:
#
# TULIP_DIR (will not be modified if already set): The Tulip installation path
# TULIP_FOUND: This variable is set to true if a valid Tulip installation has been found.
# TULIP_INCLUDE_DIR: The path where Tulip headers are located.
# TULIP_LIBRARIES: Contains path to the Tulip libraries
# TULIP_LIBRARIES_DIR: Contains path to the Tulip libraries
# TULIP_PLUGINS_DIR: Path where Tulip plugins are located
# TULIP_GLYPH_PLUGINS_DIR: Path where Tulip glyph plugins are located
# TULIP_INTERACTOR_PLUGINS_DIR: Path where Tulip interaction plugins are located
# TULIP_VIEW_PLUGINS_DIR: Path where Tulip view plugins are located
# TULIP_PERSPECTIVE_PLUGINS_DIR: Path where Tulip perspective plugins are located
# TULIP_CORE_LIBRARY: The path to the TulipCore module library.
# TULIP_OGL_LIBRARY: The path to the TulipOGL module library.
# TULIP_GUI_LIBRARY: The path to the TulipGUI module library.
# TULIP_OGDF_LIBRARY: The path to the TulipOGDF module library.
# TULIP_PYTHON_LIBRARY: The path to the TulipPython module library.
# TULIP_SHARE_DIR: Installation path for resources
# TULIP_VERSION: Complete version string.
# TULIP_MAJOR_VERSION: Major version digit.
# TULIP_MINOR_VERSION: Minor version digit.
# TULIP_PATCH_VERSION: Patch version digit.
# TULIP_USE_FILE: Additional Tulip-related macro definitions

# Define version separator (different for MSVC builds)
