find_library
------------
.. |FIND_XXX| replace:: find_library
.. |NAMES| replace:: NAMES name1 [name2 ...] [NAMES_PER_DIR]
.. |SEARCH_XXX| replace:: library
.. |SEARCH_XXX_DESC| replace:: library
.. |prefix_XXX_SUBDIR| replace:: ``<prefix>/lib``
.. |entry_XXX_SUBDIR| replace:: ``<entry>/lib``
.. |CMAKE_PREFIX_PATH_XXX| replace::
``<prefix>/lib/<arch>`` if :variable:`CMAKE_LIBRARY_ARCHITECTURE` is set,
and |CMAKE_PREFIX_PATH_XXX_SUBDIR|
.. |CMAKE_XXX_PATH| replace:: :variable:`CMAKE_LIBRARY_PATH`
.. |CMAKE_XXX_MAC_PATH| replace:: :variable:`CMAKE_FRAMEWORK_PATH`
.. |SYSTEM_ENVIRONMENT_PATH_XXX| replace:: Directories in ``LIB``.
On Windows hosts:
``<prefix>/lib/<arch>`` if :variable:`CMAKE_LIBRARY_ARCHITECTURE` is set,
and |SYSTEM_ENVIRONMENT_PREFIX_PATH_XXX_SUBDIR|,
and the directories in ``PATH`` itself.
.. |CMAKE_SYSTEM_PREFIX_PATH_XXX| replace::
``<prefix>/lib/<arch>`` if :variable:`CMAKE_LIBRARY_ARCHITECTURE` is set,
and |CMAKE_SYSTEM_PREFIX_PATH_XXX_SUBDIR|
.. |CMAKE_SYSTEM_XXX_PATH| replace::
:variable:`CMAKE_SYSTEM_LIBRARY_PATH`
.. |CMAKE_SYSTEM_XXX_MAC_PATH| replace::
:variable:`CMAKE_SYSTEM_FRAMEWORK_PATH`
.. |CMAKE_FIND_ROOT_PATH_MODE_XXX| replace::
:variable:`CMAKE_FIND_ROOT_PATH_MODE_LIBRARY`
.. include:: FIND_XXX.txt
When more than one value is given to the ``NAMES`` option this command by
default will consider one name at a time and search every directory
for it. The ``NAMES_PER_DIR`` option tells this command to consider one
directory at a time and search for all names in it.
Each library name given to the ``NAMES`` option is first considered
as a library file name and then considered with platform-specific
prefixes (e.g. ``lib``) and suffixes (e.g. ``.so``). Therefore one
may specify library file names such as ``libfoo.a`` directly.
This can be used to locate static libraries on UNIX-like systems.
If the library found is a framework, then ``<VAR>`` will be set to the full
path to the framework ``<fullPath>/A.framework``. When a full path to a
framework is used as a library, CMake will use a ``-framework A``, and a
``-F<fullPath>`` to link the framework to the target.
If the :prop_gbl:`FIND_LIBRARY_USE_LIB32_PATHS` global property is set
all search paths will be tested as normal, with ``32/`` appended, and
with all matches of ``lib/`` replaced with ``lib32/``. This property is
automatically set for the platforms that are known to need it if at
least one of the languages supported by the :command:`project` command
is enabled.
If the :prop_gbl:`FIND_LIBRARY_USE_LIB64_PATHS` global property is set
all search paths will be tested as normal, with ``64/`` appended, and
with all matches of ``lib/`` replaced with ``lib64/``. This property is
automatically set for the platforms that are known to need it if at
least one of the languages supported by the :command:`project` command
is enabled.
