# Find Magnum integration library
# -------------------------------
#
# Finds the Magnum integration library. Basic usage::
#
# find_package(MagnumIntegration REQUIRED)
#
# This command tries to find Magnum integration library and then defines the
# following:
#
# MagnumIntegration_FOUND - Whether the library was found
#
# This command alone is useless without specifying the components:
#
# Bullet - Bullet Physics integration library
# Dart - Dart Physics integration library
# Eigen - Eigen integration library
# Glm - GLM integration library
# ImGui - ImGui integration library
# Ovr - Oculus SDK integration library
#
# Example usage with specifying additional components is:
#
# find_package(MagnumIntegration REQUIRED Bullet)
#
# For each component is then defined:
#
# MagnumIntegration_*_FOUND - Whether the component was found
# MagnumIntegration::* - Component imported target
#
# The package is found if either debug or release version of each requested
# library is found. If both debug and release libraries are found, proper
# version is chosen based on actual build configuration of the project (i.e.
# Debug build is linked to debug libraries, Release build to release
# libraries).
#
# Additionally these variables are defined for internal usage:
#
# MAGNUMINTEGRATION_INCLUDE_DIR - Magnum integration include dir (w/o
# dependencies)
# MAGNUMINTEGRATION_*_LIBRARY_DEBUG - Debug version of given library, if found
# MAGNUMINTEGRATION_*_LIBRARY_RELEASE - Release version of given library, if
# found
#
#
# This file is part of Magnum.
