## Build and Install

```shell
cd /path/to/glm
cmake \
-DGLM_BUILD_TESTS=OFF \
-DBUILD_SHARED_LIBS=OFF \
-B build .
cmake --build build -- all
cmake --build build -- install
```

Passing `-DBUILD_SHARED_LIBS=ON` to build shared library

And then in your `CMakeLists.txt`:

```cmake
find_package(glm CONFIG REQUIRED)
target_link_libraries(main PRIVATE glm::glm)
```

If your perfer to use header-only version of GLM

```cmake
find_package(glm CONFIG REQUIRED)
target_link_libraries(main PRIVATE glm::glm-header-only)
```

## Vcpkg

```shell
vcpkg install glm
```
