# 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. |
