FindLibevent
|
||||
---------
|
||||
|
||||
Find Libevent include dirs and libraries
|
||||
|
||||
Use this module by invoking :command:`find_package` with the form:
|
||||
|
||||
.. code-block:: cmake
|
||||
|
||||
find_package(Libevent
|
||||
[version] [EXACT] # Minimum or EXACT version e.g. 2020.03
|
||||
[REQUIRED] # Fail with error if Libevent is not found
|
||||
[COMPONENTS <libs>...] # Libevent libraries by their canonical name
|
||||
)
|
||||
|
||||
This module finds headers and requested component libraries OR a CMake package configuration file provided by a "Libevent
|
||||
CMake" build. For the latter case skip to the :ref:`Libevent CMake` section below.
|
||||
|
||||
Result Variables
|
||||
^^^^^^^^^^^^^^^^
|
||||
|
||||
This module defines the following variables:
|
||||
|
||||
``Libevent_FOUND``
|
||||
True if headers and requested libraries were found.
|
||||
|
||||
``Libevent_INCLUDE_DIRS``
|
||||
Libevent include directories.
|
||||
|
||||
``Libevent_LIBRARY_DIRS``
|
||||
Link directories for Libevent libraries.
|
||||
|
||||
``Libevent_LIBRARIES``
|
||||
Libevent component libraries to be linked.
|
||||
|
||||
``Libevent_<COMPONENT>_FOUND``
|
||||
True if component ``<COMPONENT>`` was found (``<COMPONENT>`` name is upper-case).
|
||||
|
||||
``Libevent_<COMPONENT>_LIBRARY``
|
||||
Libraries to link for component ``<COMPONENT>`` (may include :command:`target_link_libraries` debug/optimized
|
||||
keywords).
|
||||
|
||||
``Libevent_VERSION``
|
||||
Libevent version number in ``X.Y`` format.
|
||||
|
||||
``Libevent_VERSION_MAJOR``
|
||||
Libevent major version number (``X`` in ``X.Y``).
|
||||
|
||||
``Libevent_VERSION_MINOR``
|
||||
Libevent minor version number (``Y`` in ``X.Y``).
|
||||
|
||||
Cache variables
|
||||
^^^^^^^^^^^^^^^
|
||||
|
||||
Search results are saved persistently in CMake cache entries:
|
||||
|
||||
``Libevent_INCLUDE_DIR``
|
||||
Directory containing Libevent headers.
|
||||
|
||||
``Libevent_LIBRARY_DIR_RELEASE``
|
||||
Directory containing release Libevent libraries.
|
||||
|
||||
``Libevent_LIBRARY_DIR_DEBUG``
|
||||
Directory containing debug Libevent libraries.
|
||||
|
||||
``Libevent_<COMPONENT>_LIBRARY_DEBUG``
|
||||
Component ``<COMPONENT>`` library debug variant.
|
||||
|
||||
``Libevent_<COMPONENT>_LIBRARY_RELEASE``
|
||||
Component ``<COMPONENT>`` library release variant.
|
||||
|
||||
Hints
|
||||
^^^^^
|
||||
|
||||
This module reads hints about search locations from variables:
|
||||
|
||||
``Libevent_ROOT``, ``LibeventROOT``
|
||||
Preferred installation prefix.
|
||||
|
||||
``Libevent_INCLUDEDIR``
|
||||
Preferred include directory e.g. ``<prefix>/include``.
|
||||
|
||||
``Libevent_LIBRARYDIR``
|
||||
Preferred library directory e.g. ``<prefix>/lib``.
|
||||
|
||||
``Libevent_NO_SYSTEM_PATHS``
|
||||
Set to ``ON`` to disable searching in locations not specified by these hint variables. Default is ``OFF``.
|
||||
|
||||
Users may set these hints or results as ``CACHE`` entries. Projects should not read these entries directly but
|
||||
instead use the above result variables. Note that some hint names start in upper-case ``Libevent``. One may specify these
|
||||
as environment variables if they are not specified as CMake variables or cache entries.
|
||||
|
||||
This module first searches for the Libevent header files using the above hint variables (excluding ``Libevent_LIBRARYDIR``) and
|
||||
saves the result in ``Libevent_INCLUDE_DIR``. Then it searches for requested component libraries using the above hints
|
||||
(excluding ``Libevent_INCLUDEDIR``), "lib" directories near ``Libevent_INCLUDE_DIR``, and the library name configuration
|
||||
settings below. It saves the library directories in ``Libevent_LIBRARY_DIR_DEBUG`` and ``Libevent_LIBRARY_DIR_RELEASE`` and
|
||||
individual library locations in ``Libevent_<COMPONENT>_LIBRARY_DEBUG`` and ``Libevent_<COMPONENT>_LIBRARY_RELEASE``. When one
|
||||
changes settings used by previous searches in the same build tree (excluding environment variables) this module
|
||||
discards previous search results affected by the changes and searches again.
|
||||
|
||||
Imported Targets
|
||||
^^^^^^^^^^^^^^^^
|
||||
|
||||
This module defines the following :prop_tgt:`IMPORTED` targets:
|
||||
|
||||
``Libevent::<component>``
|
||||
Target for specific component dependency (shared or static library); ``<component>`` name is lower-case.
|
||||
|
||||
It is important to note that the imported targets behave differently than variables created by this module: multiple
|
||||
calls to :command:`find_package(Libevent)` in the same directory or sub-directories with different options (e.g. static or
|
||||
shared) will not override the values of the targets created by the first call.
|
||||
|
||||
Other Variables
|
||||
^^^^^^^^^^^^^^^
|
||||
|
||||
Libevent libraries come in many variants encoded in their file name. Users or projects may tell this module which variant
|
||||
to find by setting variables:
|
||||
|
||||
``Libevent_FIND_RELEASE_ONLY``
|
||||
Set to ``ON`` or ``OFF`` to specify whether to restrict the search to release libraries only. Default is ``OFF``.
|
||||
|
||||
``Libevent_USE_DEBUG_LIBS``
|
||||
Set to ``ON`` or ``OFF`` to specify whether to search and use the debug libraries. Default is ``ON`` (except when
|
||||
Libevent_FIND_RELEASE_ONLY is ``ON``).
|
||||
|
||||
``Libevent_USE_RELEASE_LIBS``
|
||||
Set to ``ON`` or ``OFF`` to specify whether to search and use the release libraries. Default is ``ON``.
|
||||
|
||||
Other variables one may set to control this module are:
|
||||
|
||||
``Libevent_DEBUG``
|
||||
Set to ``ON`` to enable debug output from ``FindLibevent``. Please enable this before filing any bug report.
|
||||
|
||||
``Libevent_LIBRARY_DIR``
|
||||
Default value for ``Libevent_LIBRARY_DIR_RELEASE`` and ``Libevent_LIBRARY_DIR_DEBUG``.
|
||||
|
||||
|
||||
Examples
|
||||
^^^^^^^^
|
||||
|
||||
Find Libevent headers only:
|
||||
|
||||
.. code-block:: cmake
|
||||
|
||||
find_package(Libevent 2.0.0)
|
||||
if(Libevent_FOUND)
|
||||
include_directories(${Libevent_INCLUDE_DIRS})
|
||||
add_executable(foo foo.cc)
|
||||
target_link_libraries(foo PUBLIC Libevent::Libevent)
|
||||
endif()
|
||||
|
||||
Find Libevent libraries and use imported targets:
|
||||
|
||||
.. code-block:: cmake
|
||||
|
||||
find_package(Libevent 2.0.0 REQUIRED COMPONENTS Libevent)
|
||||
add_executable(foo foo.cc)
|
||||
target_link_libraries(foo PUBLIC Libevent::Libevent)
|
||||
|
||||
Find Libevent headers and some *static* (release only) libraries:
|
||||
|
||||
.. code-block:: cmake
|
||||
|
||||
set(Libevent_USE_DEBUG_LIBS OFF) # ignore debug libs and
|
||||
set(Libevent_USE_RELEASE_LIBS ON) # only find release libs
|
||||
find_package(Libevent 2.0.0 COMPONENTS Libevent)
|
||||
if(Libevent_FOUND)
|
||||
add_executable(foo foo.cc)
|
||||
target_link_libraries(foo PUBLIC Libevent::Libevent)
|
||||
endif()
|
||||
|
||||
.. _`Libevent CMake`:
|
||||
|
||||
Libevent CMake
|
||||
^^^^^^^^^^^
|
||||
|
||||
If Libevent was built using CMake, it provides a package configuration file for use with find_package's config mode.
|
||||
This module looks for the package configuration file called ``LibeventConfig.cmake`` and stores the result in ``CACHE``
|
||||
entry ``Libevent_DIR``. If found, the package configuration file is loaded and this module returns with no further action.
|
||||
See documentation of the Libevent CMake package configuration for details on what it provides.
|
||||
|
||||
Set ``Libevent_NO_CMAKE`` to ``ON``, to disable the search for the package using the CONFIG method.
|
||||
|
||||
.. _`Libevent pkg-config`:
|
||||
|
||||
Libevent CMake
|
||||
^^^^^^^^^^^
|
||||
|
||||
If Libevent was installed with its pkg-config files, this module may attempt to look for Libevent by relying on pkg-config.
|
||||
If the components are found using this method, this module returns with no further action.
|
||||
|
||||
Set ``Libevent_NO_PKGCONFIG`` to ``ON``, to disable the search for the package using the pkg-config method.
