#
# DO NOT EDIT THIS FILE OR YOU WILL DAMAGE ALL YOUR CONFIGURATION
#
# Try to find a CamiTK installation or build tree (CAMITK_DIR)
# If CamiTK is not found, CAMITK_FOUND is set to false.
#
# This module can be used to find CamiTK.
#
# To use this file, you just need to have the path to it in your
# CMAKE_MODULE_PATH and add this line to your CMakeLists.txt
#
# find_package(CamiTK ${CAMITK_VERSION} REQUIRED)
#
# where CAMITK_VERSION is the minimal needed version (e.g. "3.2")
#
# Once done, just add this line to your CMakeLists.txt:
# include("${CAMITK_USE_FILE}")
# et voilà!
#
# Once this module has run, the following variables will be properly defined
#  CAMITK_FOUND            - system has CamiTK
#  CAMITK_DIR              - root installation for CamiTK (at least the SDK)
#  CAMITK_USE_FILE         - CMake file to use CamiTK (CamiTKConfig.cmake)
#  CAMITK_VERSION_MAJOR    - CamiTK major version number.
#  CAMITK_VERSION_MINOR    - CamiTK minor version number
