# Config file for Ceres Solver - Find Ceres & dependencies.
#
# This file is used by CMake when find_package(Ceres) is invoked and either
# the directory containing this file either is present in CMAKE_MODULE_PATH
# (if Ceres was installed), or exists in the local CMake package registry if
# the Ceres build directory was exported.
#
# This module defines the following variables:
#
# Ceres_FOUND / CERES_FOUND: True if Ceres has been successfully
# found. Both variables are set as although
# FindPackage() only references Ceres_FOUND
# in Config mode, given the conventions for
# <package>_FOUND when FindPackage() is
# called in Module mode, users could
# reasonably expect to use CERES_FOUND
# instead.
#
# CERES_VERSION: Version of Ceres found.
#
# CERES_INCLUDE_DIRS: Include directories for Ceres and the
# dependencies which appear in the Ceres public
# API and are thus required to use Ceres.
#
# CERES_LIBRARIES: Libraries for Ceres and all
# dependencies against which Ceres was
# compiled. This will not include any optional
# dependencies that were disabled when Ceres was
# compiled.
#
# The following variables are also defined for legacy compatibility
# only. Any new code should not use them as they do not conform to
# the standard CMake FindPackage naming conventions.
#
# CERES_INCLUDES = ${CERES_INCLUDE_DIRS}.
# Called if we failed to find Ceres or any of its required dependencies,
# unsets all public (designed to be used externally) variables and reports
# error message at priority depending upon [REQUIRED/QUIET/<NONE>] argument.
