### <a name="section1_5"></a> 1.5. Finding GLM with CMake
GLM provides the CMake package configuration files `glmConfig.cmake` and `glmConfig-version.cmake`.
When installed, GLM provides the CMake package configuration files `glmConfig.cmake` and `glmConfigVersion.cmake`.
To use these configurations files, you may need to set the `glm_DIR` variable to the directory containing the configuration files `<path to glm root>/cmake/glm/`.
To use these configurations files, you may need to set the `glm_DIR` variable to the directory containing the configuration files `<installation prefix>/lib/cmake/glm/`.
Use the `find_package` CMake command to load the configurations into your project. Lastly, either link your executable against the `glm::glm` target or add `${GLM_INCLUDE_DIRS}` to your target's include directories:
```cmake
set(glm_DIR <path to glm root>/cmake/glm) # if necessary
set(glm_DIR <installation prefix>/lib/cmake/glm) # if necessary
find_package(glm REQUIRED)
target_link_libraries(<your executable> glm::glm)
```
To use GLM as a submodule in a project instead, use `add_subdirectory` to expose the same target, or add the directory to your target's
```cmake
add_subdirectory(glm)
target_link_libraries(<your executable> glm::glm)
# or
target_include_directories(<your executable> glm)
```
