@section build_link Link with the right libraries
@subsection build_link_cmake Using GLFW from CMake
The `GLFW_LIBRARIES` cache variable contains all link-time dependencies of GLFW
as it is currently configured, so to link against GLFW simply do:
target_link_libraries(myapp glfw ${GLFW_LIBRARIES})
Note that this does not include GLU, as GLFW does not use it. If your
application needs GLU, you can add it to the list of dependencies with the
`OPENGL_glu_LIBRARY` cache variable.
@subsection build_link_win32 Windows
@subsection build_link_win32 With any toolchain on Windows
The static version of the GLFW library is named `glfw3`. When using this
version, it is also necessary to link with some libraries that GLFW uses.

@subsection build_link_cmake With CMake and GLFW source
You can use the GLFW source tree directly from a project that uses CMake. This
way, GLFW will be built along with your application as needed.
Firstly, add the root directory of the GLFW source tree to your project. This
will add the `glfw` target and the necessary cache variables to your project.
add_subdirectory(path/to/glfw)
To be able to include the GLFW header from your code, you need to tell the
compiler where to find it.
include_directories(path/to/glfw/include)
Once GLFW has been added to the project, the `GLFW_LIBRARIES` cache variable
contains all link-time dependencies of GLFW as it is currently configured. To
link against GLFW, link against them and the `glfw` target.
target_link_libraries(myapp glfw ${GLFW_LIBRARIES})
Note that `GLFW_LIBRARIES` does not include GLU, as GLFW does not use it. If
your application needs GLU, you can add it to the list of dependencies with the
`OPENGL_glu_LIBRARY` cache variable, which is implicitly created when the GLFW
CMake files look for OpenGL.
target_link_libraries(myapp glfw ${OPENGL_glu_LIBRARY} ${GLFW_LIBRARIES})
@subsection build_link_cmake With CMake on Unix and installed GLFW binaries
CMake can import settings from pkg-config, which GLFW supports. When you
installed GLFW, the pkg-config file `glfw3.pc` was installed along with it.
First you need to find the PkgConfig package. If this fails, you may need to
install the pkg-config package for your distribution.
find_package(PkgConfig REQUIRED)
This creates the CMake commands to find pkg-config packages. Then you need to
find the GLFW package.
pkg_search_module(GLFW REQUIRED glfw3)
This creates the CMake variables you need to use GLFW. To be able to include
the GLFW header, you need to tell your compiler where it is.
include_directories(${GLFW_INCLUDE_DIRS})
You also need to link against the correct libraries. If you are using the
shared library version of GLFW, use the `GLFW_LIBRARIES` variable.
target_link_libraries(simple ${GLFW_LIBRARIES})
If you are using the static library version of GLFW, use the
`GLFW_STATIC_LIBRARIES` variable.
target_link_libraries(simple ${GLFW_STATIC_LIBRARIES})
@subsection build_link_pkgconfig With pkg-config on OS X or other Unix
GLFW supports [pkg-config](http://www.freedesktop.org/wiki/Software/pkg-config/),
and `glfw3.pc` file is generated when the library is built and installed along
with it. You can use it without installation using the `PKG_CONFIG_PATH`
environment variable. See the documentation for pkg-config for more details.

If you are using the shared library, simply omit the `--static` flag.
If you are using GLU, you should also add `-lGLU` to your link flags.
cc `pkg-config --cflags glfw3` -o myprog myprog.c `pkg-config --libs glfw3`
You can also use the `glfw3.pc` file without installing it first, by using the
`PKG_CONFIG_PATH` environment variable.
env PKG_CONFIG_PATH=path/to/glfw/src cc `pkg-config --cflags glfw3` -o myprog myprog.c `pkg-config --static --libs glfw3`
The dependencies do not include GLU, as GLFW does not need it. On OS X, GLU is
built into the OpenGL framework, so if you need GLU you don't need to do
anything extra. If you need GLU and are using Linux or BSD, you should add
`-lGLU` to your link flags.
See the manpage and other documentation for pkg-config and your compiler and
linker for more information on how to link programs.
@subsection build_link_osx Mac OS X
@subsection build_link_xcode With Xcode on OS X
GLFW on Mac OS X uses the Cocoa, OpenGL and IOKit frameworks.
If you are using the dynamic library version of GLFW, simply add it to the
project dependencies.
If you are using Xcode, you can simply add the GLFW library and these frameworks
as dependencies.
If you are using the static library version of GLFW, add it and the Cocoa,
OpenGL and IOKit frameworks to the project as dependencies.
If you are building from the
command-line, it is recommended that you use pkg-config
GLFW supports [pkg-config](http://www.freedesktop.org/wiki/Software/pkg-config/),

You can find pkg-config in most package systems such as
[Fink](http://www.finkproject.org/) and [MacPorts](http://www.macports.org/), so
if you have one of them installed, simply install pkg-config. Once you have
pkg-config available, the command-line for compiling and linking your
program is:
cc `pkg-config --cflags glfw3` -o myprog myprog.c `pkg-config --static --libs glfw3`
