#
|

|
# Optional COMPONENTS
|
||||||
|
# ^^^^^^^^^^^^^^^^^^^
|
||||||
|
#
|
||||||
|
# This module respects several optional COMPONENTS: ``EGL``, ``GLX``, and
|
||||||
|
# ``OpenGL``. 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::GL``
|
||||||
|
# ``OpenGL::GLU``
|
||||||
|
# Defined if the system has GLU.
|
||||||
|
# ``OpenGL::GLX``
|
||||||
|
# Defined if the system has 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).
|
||||||
|
#
|
||||||
|
# ``LEGACY``
|
||||||
|
# Prefer to use the legacy libGL library, if available.
|
||||||
|
# This is the default if no components were requested.
|
||||||
|
#
|
||||||
|
# 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.

||||||

FindPackageHandleStandardArgs
|
||||||
|
-----------------------------
|
||||||
|
|
||||||
|
This module provides a function intended to be used in :ref:`Find Modules`
|
||||||
|
implementing :command:`find_package(<PackageName>)` calls. It handles the
|
||||||
|
``REQUIRED``, ``QUIET`` and version-related arguments of ``find_package``.
|
||||||
|
It also sets the ``<PackageName>_FOUND`` variable. The package is
|
||||||
|
considered found if all variables listed contain valid results, e.g.
|
||||||
|
valid filepaths.
|
||||||
|
|
||||||
|
.. command:: find_package_handle_standard_args
|
||||||
|
|
||||||
|
There are two signatures::
|
||||||
|
|
||||||
|
find_package_handle_standard_args(<PackageName>
|
||||||
|
(DEFAULT_MSG|<custom-failure-message>)
|
||||||
|
<required-var>...
|
||||||
|
)
|
||||||
|
|
||||||
|
find_package_handle_standard_args(<PackageName>
|
||||||
|
[FOUND_VAR <result-var>]
|
||||||
|
[REQUIRED_VARS <required-var>...]
|
||||||
|
[VERSION_VAR <version-var>]
|
||||||
|
[HANDLE_COMPONENTS]
|
||||||
|
[CONFIG_MODE]
|
||||||
|
[FAIL_MESSAGE <custom-failure-message>]
|
||||||
|
)
|
||||||
|
|
||||||
|
The ``<PackageName>_FOUND`` variable will be set to ``TRUE`` if all
|
||||||
|
the variables ``<required-var>...`` are valid and any optional
|
||||||
|
constraints are satisfied, and ``FALSE`` otherwise. A success or
|
||||||
|
failure message may be displayed based on the results and on
|
||||||
|
whether the ``REQUIRED`` and/or ``QUIET`` option was given to
|
||||||
|
the :command:`find_package` call.
|
||||||
|
|
||||||
|
The options are:
|
||||||
|
|
||||||
|
``(DEFAULT_MSG|<custom-failure-message>)``
|
||||||
|
In the simple signature this specifies the failure message.
|
||||||
|
Use ``DEFAULT_MSG`` to ask for a default message to be computed
|
||||||
|
(recommended). Not valid in the full signature.
|
||||||
|
|
||||||
|
``FOUND_VAR <result-var>``
|
||||||
|
Obsolete. Specifies either ``<PackageName>_FOUND`` or
|
||||||
|
``<PACKAGENAME>_FOUND`` as the result variable. This exists only
|
||||||
|
for compatibility with older versions of CMake and is now ignored.
|
||||||
|
Result variables of both names are always set for compatibility.
|
||||||
|
|
||||||
|
``REQUIRED_VARS <required-var>...``
|
||||||
|
Specify the variables which are required for this package.
|
||||||
|
These may be named in the generated failure message asking the
|
||||||
|
user to set the missing variable values. Therefore these should
|
||||||
|
typically be cache entries such as ``FOO_LIBRARY`` and not output
|
||||||
|
variables like ``FOO_LIBRARIES``.
|
||||||
|
|
||||||
|
``VERSION_VAR <version-var>``
|
||||||
|
Specify the name of a variable that holds the version of the package
|
||||||
|
that has been found. This version will be checked against the
|
||||||
|
(potentially) specified required version given to the
|
||||||
|
:command:`find_package` call, including its ``EXACT`` option.
|
||||||
|
The default messages include information about the required
|
||||||
|
version and the version which has been actually found, both
|
||||||
|
if the version is ok or not.
|
||||||
|
|
||||||
|
``HANDLE_COMPONENTS``
|
||||||
|
Enable handling of package components. In this case, the command
|
||||||
|
will report which components have been found and which are missing,
|
||||||
|
and the ``<PackageName>_FOUND`` variable will be set to ``FALSE``
|
||||||
|
if any of the required components (i.e. not the ones listed after
|
||||||
|
the ``OPTIONAL_COMPONENTS`` option of :command:`find_package`) are
|
||||||
|
missing.
|
||||||
|
|
||||||
|
``CONFIG_MODE``
|
||||||
|
Specify that the calling find module is a wrapper around a
|
||||||
|
call to ``find_package(<PackageName> NO_MODULE)``. This implies
|
||||||
|
a ``VERSION_VAR`` value of ``<PackageName>_VERSION``. The command
|
||||||
|
will automatically check whether the package configuration file
|
||||||
|
was found.
|
||||||
|
|
||||||
|
``FAIL_MESSAGE <custom-failure-message>``
|
||||||
|
Specify a custom failure message instead of using the default
|
||||||
|
generated message. Not recommended.
|
||||||
|
|
||||||
|
Example for the simple signature:
|
||||||
|
|
||||||
|
.. code-block:: cmake
|
||||||
|
|
||||||
|
find_package_handle_standard_args(LibXml2 DEFAULT_MSG
|
||||||
|
LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)
|
||||||
|
|
||||||
|
The ``LibXml2`` package is considered to be found if both
|
||||||
|
``LIBXML2_LIBRARY`` and ``LIBXML2_INCLUDE_DIR`` are valid.
|
||||||
|
Then also ``LibXml2_FOUND`` is set to ``TRUE``. If it is not found
|
||||||
|
and ``REQUIRED`` was used, it fails with a
|
||||||
|
:command:`message(FATAL_ERROR)`, independent whether ``QUIET`` was
|
||||||
|
used or not. If it is found, success will be reported, including
|
||||||
|
the content of the first ``<required-var>``. On repeated CMake runs,
|
||||||
|
the same message will not be printed again.
|
||||||
|
|
||||||
|
Example for the full signature:
|
||||||
|
|
||||||
|
.. code-block:: cmake
|
||||||
|
|
||||||
|
find_package_handle_standard_args(LibArchive
|
||||||
|
REQUIRED_VARS LibArchive_LIBRARY LibArchive_INCLUDE_DIR
|
||||||
|
VERSION_VAR LibArchive_VERSION)
|
||||||
|
|
||||||
|
In this case, the ``LibArchive`` package is considered to be found if
|
||||||
|
both ``LibArchive_LIBRARY`` and ``LibArchive_INCLUDE_DIR`` are valid.
|
||||||
|
Also the version of ``LibArchive`` will be checked by using the version
|
||||||
|
contained in ``LibArchive_VERSION``. Since no ``FAIL_MESSAGE`` is given,
|
||||||
|
the default messages will be printed.
|
||||||
|
|
||||||
|
Another example for the full signature:
|
||||||
|
|
||||||
|
.. code-block:: cmake
|
||||||
|
|
||||||
|
find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
|
||||||
|
find_package_handle_standard_args(Automoc4 CONFIG_MODE)
|
||||||
|
|
||||||
|
In this case, a ``FindAutmoc4.cmake`` module wraps a call to
|
||||||
|
``find_package(Automoc4 NO_MODULE)`` and adds an additional search
|
||||||
|
directory for ``automoc4``. Then the call to
|
||||||
|
``find_package_handle_standard_args`` produces a proper success/failure
|
||||||
|
message.

# will print a message once for each unique find result. This is useful

# for telling the user where a package was found. The first argument

# specifies the message to display. The third argument lists details
|
||||||

# displayed again. The macro also obeys the QUIET argument to the
|

|
# find_package command.
