# 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/glm.hpp OR # /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. #============================================================================= # Copyright 2012 Carsten Neumann # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.) # default search dirs SET(_glm_HEADER_SEARCH_DIRS "/usr/include" "/usr/local/include") # check environment variable SET(_glm_ENV_ROOT_DIR "$ENV{GLM_ROOT_DIR}") IF(NOT GLM_ROOT_DIR AND _glm_ENV_ROOT_DIR) SET(GLM_ROOT_DIR "${_glm_ENV_ROOT_DIR}") ENDIF(NOT GLM_ROOT_DIR AND _glm_ENV_ROOT_DIR) # put user specified location at beginning of search IF(GLM_ROOT_DIR) SET(_glm_HEADER_SEARCH_DIRS "${GLM_ROOT_DIR}" "${GLM_ROOT_DIR}/include" ${_glm_HEADER_SEARCH_DIRS}) ENDIF(GLM_ROOT_DIR) # locate header FIND_PATH(GLM_INCLUDE_DIR "glm/glm.hpp" PATHS ${_glm_HEADER_SEARCH_DIRS}) INCLUDE(FindPackageHandleStandardArgs) FIND_PACKAGE_HANDLE_STANDARD_ARGS(GLM DEFAULT_MSG GLM_INCLUDE_DIR) IF(GLM_FOUND) SET(GLM_INCLUDE_DIRS "${GLM_INCLUDE_DIR}") MESSAGE(STATUS "GLM_INCLUDE_DIR = ${GLM_INCLUDE_DIR}") ENDIF(GLM_FOUND)
