It is now required to specify which modules to find, as only these
modules will be searched for.

# Find Magnum - Magnum handling module for CMake
# - Find Magnum
#
# This module depends on Corrade and additionally defines:
# Basic usage:
#
# MAGNUM_FOUND - True if Magnum library is found
# MAGNUM_INCLUDE_DIR - Include dir for Magnum
# MAGNUM_LIBRARY - Magnum library
# MAGNUM_PHYSICS_LIBRARY - Magnum physics library
# MAGNUM_PRIMITIVES_LIBRARY - Library with primitives
# find_package(Magnum [REQUIRED])
#
# MAGNUM_LIBRARY_INSTALL_DIR - Library installation directory
# MAGNUM_CMAKE_MODULE_INSTALL_DIR - Installation dir for CMake modules
# MAGNUM_INCLUDE_INSTALL_DIR - Include installation directory for headers
# This command tries to find Magnum library and then defines:
#
# MAGNUM_FOUND - Whether the library was found
# MAGNUM_LIBRARY - Magnum library
# MAGNUM_INCLUDE_DIR - Root include dir
# MAGNUM_PLUGINS_IMPORTER_DIR - Directory with importer plugins
#
# This command will try to find only the base library, not the optional
# components. The base library depends on Corrade, OpenGL and GLEW libraries.
# Additional dependencies are specified by the components. The optional
# components are:
#
# MeshTools - MeshTools library
# Physics - Physics library
# Primitives - Library with stock geometric primitives (static)
# Shaders - Library with stock shaders
#
# Example usage with specifying additional components is:
#
# find_package(Magnum [REQUIRED|COMPONENTS] MeshTools Primitives GlutContext)
#
# For each component is then defined:
#
# MAGNUM_*_FOUND - Whether the component was found
# MAGNUM_*_LIBRARY - Component library
#
# Additionally these variables are defined for internal usage:
#
# MAGNUM_LIBRARY_INSTALL_DIR - Library installation directory
# MAGNUM_PLUGINS_INSTALL_DIR - Plugin installation directory
# MAGNUM_PLUGINS_IMPORTER_INSTALL_DIR - Importer plugin installation directory
# MAGNUM_CMAKE_MODULE_INSTALL_DIR - Installation dir for CMake modules
# MAGNUM_INCLUDE_INSTALL_DIR - Header installation directory
# MAGNUM_PLUGINS_INCLUDE_INSTALL_DIR - Plugin header installation directory
#
# Dependencies
