# FindGLM - attempts to locate the glm matrix/vector library.
# #
# This module defines the following variables (on success): # FindGLM.cmake
# GLM_INCLUDE_DIRS - where to find glm/glm.hpp
# GLM_FOUND - if the library was successfully located
#
# It is trying a few standard installation locations, but can be customized
# with the following variables:
# GLM_ROOT_DIR - root directory of a glm installation
# Headers are expected to be found in either:
# <GLM_ROOT_DIR>/glm/glm.hpp OR
# <GLM_ROOT_DIR>/include/glm/glm.hpp
# This variable can either be a cmake or environment
# variable. Note however that changing the value
# of the environment varible will NOT result in
# re-running the header search and therefore NOT
# adjust the variables set by this module.
# This is a modified version of the FindGLM module included with CMake.
