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_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.
