  1. # FindGLM - attempts to locate the glm matrix/vector library.
  2. #
  3. # This module defines the following variables (on success):
  4. # GLM_INCLUDE_DIRS - where to find glm/glm.hpp
  5. # GLM_FOUND - if the library was successfully located
  6. #
  7. # It is trying a few standard installation locations, but can be customized
  8. # with the following variables:
  9. # GLM_ROOT_DIR - root directory of a glm installation
  10. # Headers are expected to be found in either:
  11. # <GLM_ROOT_DIR>/glm/glm.hpp OR
  12. # <GLM_ROOT_DIR>/include/glm/glm.hpp
  13. # This variable can either be a cmake or environment
  14. # variable. Note however that changing the value
  15. # of the environment varible will NOT result in
  16. # re-running the header search and therefore NOT
  17. # adjust the variables set by this module.
