# FindGLM - attempts to locate the glm matrix/vector library.
|
|
#
|
|
# This module defines the following variables (on success):
|
|
# 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.
