There are corresponding import targets for each of these flags. - -IMPORTED Targets -^^^^^^^^^^^^^^^^ - -This module defines the :prop_tgt:`IMPORTED` targets: - -``OpenGL::GL`` - Defined to the platform-specific OpenGL libraries if the system has OpenGL. -``OpenGL::OpenGL`` - Defined to libOpenGL if the system is GLVND-based. -``OpenGL::GLU`` - Defined if the system has OpenGL Utility Library (GLU). -``OpenGL::GLX`` - Defined if the system has OpenGL Extension to the X Window System (GLX). -``OpenGL::EGL`` - Defined if the system has EGL. - -Result Variables -^^^^^^^^^^^^^^^^ - -This module sets the following variables: - -``OPENGL_FOUND`` - True, if the system has OpenGL and all components are found. -``OPENGL_XMESA_FOUND`` - True, if the system has XMESA. -``OPENGL_GLU_FOUND`` - True, if the system has GLU. -``OpenGL_OpenGL_FOUND`` - True, if the system has an OpenGL library. -``OpenGL_GLX_FOUND`` - True, if the system has GLX. -``OpenGL_EGL_FOUND`` - True, if the system has EGL. -``OPENGL_INCLUDE_DIR`` - Path to the OpenGL include directory. -``OPENGL_EGL_INCLUDE_DIRS`` - Path to the EGL include directory. -``OPENGL_LIBRARIES`` - Paths to the OpenGL library, windowing system libraries, and GLU libraries. - On Linux, this assumes GLX and is never correct for EGL-based targets. - Clients are encouraged to use the ``OpenGL::*`` import targets instead. - -Cache variables -^^^^^^^^^^^^^^^ - -The following cache variables may also be set: - -``OPENGL_egl_LIBRARY`` - Path to the EGL library. -``OPENGL_glu_LIBRARY`` - Path to the GLU library. -``OPENGL_glx_LIBRARY`` - Path to the GLVND 'GLX' library. -``OPENGL_opengl_LIBRARY`` - Path to the GLVND 'OpenGL' library -``OPENGL_gl_LIBRARY`` - Path to the OpenGL library. New code should prefer the ``OpenGL::*`` import - targets. - -Linux-specific -^^^^^^^^^^^^^^ - -Some Linux systems utilize GLVND as a new ABI for OpenGL. GLVND separates -context libraries from OpenGL itself; OpenGL lives in "libOpenGL", and -contexts are defined in "libGLX" or "libEGL". GLVND is currently the only way -to get OpenGL 3+ functionality via EGL in a manner portable across vendors. -Projects may use GLVND explicitly with target ``OpenGL::OpenGL`` and either -``OpenGL::GLX`` or ``OpenGL::EGL``. - -Projects may use the ``OpenGL::GL`` target (or ``OPENGL_LIBRARIES`` variable) -to use legacy GL interfaces. These will use the legacy GL library located -by ``OPENGL_gl_LIBRARY``, if available. If ``OPENGL_gl_LIBRARY`` is empty or -not found and GLVND is available, the ``OpenGL::GL`` target will use GLVND -``OpenGL::OpenGL`` and ``OpenGL::GLX`` (and the ``OPENGL_LIBRARIES`` -variable will use the corresponding libraries). Thus, for non-EGL-based -Linux targets, the ``OpenGL::GL`` target is most portable. - -A ``OpenGL_GL_PREFERENCE`` variable may be set to specify the preferred way -to provide legacy GL interfaces in case multiple choices are available. -The value may be one of: - -``GLVND`` - If the GLVND OpenGL and GLX libraries are available, prefer them. - This forces ``OPENGL_gl_LIBRARY`` to be empty. - This is the default if components were requested (since components - correspond to GLVND libraries) or if policy :policy:`CMP0072` is - set to ``NEW``. - -``LEGACY`` - Prefer to use the legacy libGL library, if available. - This is the default if no components were requested and - policy :policy:`CMP0072` is not set to ``NEW``. - -For EGL targets the client must rely on GLVND support on the user's system. -Linking should use the ``OpenGL::OpenGL OpenGL::EGL`` targets. Using GLES* -libraries is theoretically possible in place of ``OpenGL::OpenGL``, but this -module does not currently support that; contributions welcome. - -``OPENGL_egl_LIBRARY`` and ``OPENGL_EGL_INCLUDE_DIRS`` are defined in the case of -GLVND. For non-GLVND Linux and other systems these are left undefined. - -macOS-Specific -^^^^^^^^^^^^^^ - -On OSX FindOpenGL defaults to using the framework version of OpenGL. People -will have to change the cache values of OPENGL_glu_LIBRARY and -OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX. -#]=======================================================================] - -set(_OpenGL_REQUIRED_VARS OPENGL_gl_LIBRARY) - -# Provide OPENGL_USE_<C> variables for each component. -foreach(component ${OpenGL_FIND_COMPONENTS}) - string(TOUPPER ${component} _COMPONENT) - set(OPENGL_USE_${_COMPONENT} 1) -endforeach() - -if (CYGWIN) - find_path(OPENGL_INCLUDE_DIR GL/gl.h ) - list(APPEND _OpenGL_REQUIRED_VARS OPENGL_INCLUDE_DIR) - - find_library(OPENGL_gl_LIBRARY opengl32 ) - find_library(OPENGL_glu_LIBRARY glu32 ) - -elseif (WIN32) - - if(BORLAND) - set (OPENGL_gl_LIBRARY import32 CACHE STRING "OpenGL library for win32") - set (OPENGL_glu_LIBRARY import32 CACHE STRING "GLU library for win32") - else() - set (OPENGL_gl_LIBRARY opengl32 CACHE STRING "OpenGL library for win32") - set (OPENGL_glu_LIBRARY glu32 CACHE STRING "GLU library for win32") - endif() - -elseif (APPLE) - # The OpenGL.framework provides both gl and glu - find_library(OPENGL_gl_LIBRARY OpenGL DOC "OpenGL library for OS X") - find_library(OPENGL_glu_LIBRARY OpenGL DOC - "GLU library for OS X (usually same as OpenGL library)") - find_path(OPENGL_INCLUDE_DIR OpenGL/gl.h DOC "Include for OpenGL on OS X") - list(APPEND _OpenGL_REQUIRED_VARS OPENGL_INCLUDE_DIR) - -else() - if (CMAKE_SYSTEM_NAME MATCHES "HP-UX") - # Handle HP-UX cases where we only want to find OpenGL in either hpux64 - # or hpux32 depending on if we're doing a 64 bit build. - if(CMAKE_SIZEOF_VOID_P EQUAL 4) - set(_OPENGL_LIB_PATH - /opt/graphics/OpenGL/lib/hpux32/) - else() - set(_OPENGL_LIB_PATH - /opt/graphics/OpenGL/lib/hpux64/ - /opt/graphics/OpenGL/lib/pa20_64) - endif() - elseif(CMAKE_SYSTEM_NAME STREQUAL Haiku) - set(_OPENGL_LIB_PATH - /boot/develop/lib/x86) - set(_OPENGL_INCLUDE_PATH - /boot/develop/headers/os/opengl) - endif() - - # The first line below is to make sure that the proper headers - # are used on a Linux machine with the NVidia drivers installed. - # They replace Mesa with NVidia's own library but normally do not - # install headers and that causes the linking to - # fail since the compiler finds the Mesa headers but NVidia's library. - # Make sure the NVIDIA directory comes BEFORE the others. - # - Atanas Georgiev <atanas@cs.columbia.edu> - find_path(OPENGL_INCLUDE_DIR GL/gl.h - /usr/share/doc/NVIDIA_GLX-1.0/include - /usr/openwin/share/include - /opt/graphics/OpenGL/include - ${_OPENGL_INCLUDE_PATH} - ) - find_path(OPENGL_GLX_INCLUDE_DIR GL/glx.h ${_OPENGL_INCLUDE_PATH}) - find_path(OPENGL_EGL_INCLUDE_DIR EGL/egl.h ${_OPENGL_INCLUDE_PATH}) - find_path(OPENGL_xmesa_INCLUDE_DIR GL/xmesa.h - /usr/share/doc/NVIDIA_GLX-1.0/include - /usr/openwin/share/include - /opt/graphics/OpenGL/include - ) - - # Search for the GLVND libraries.
