Suggest in the NAMES option that unversioned names go first to prefer local builds over distro-provided files.

A short-hand signature is:
|
|
|
|
.. parsed-literal::
|
|
|
|
|FIND_XXX| (<VAR> name1 [path1 path2 ...])
|
|
|
|
The general signature is:
|
|
|
|
.. parsed-literal::
|
|
|
|
|FIND_XXX| (
|
|
<VAR>
|
|
name | |NAMES|
|
|
[HINTS path1 [path2 ... ENV var]]
|
|
[PATHS path1 [path2 ... ENV var]]
|
|
[PATH_SUFFIXES suffix1 [suffix2 ...]]
|
|
[DOC "cache documentation string"]
|
|
[NO_DEFAULT_PATH]
|
|
[NO_CMAKE_ENVIRONMENT_PATH]
|
|
[NO_CMAKE_PATH]
|
|
[NO_SYSTEM_ENVIRONMENT_PATH]
|
|
[NO_CMAKE_SYSTEM_PATH]
|
|
[CMAKE_FIND_ROOT_PATH_BOTH |
|
|
ONLY_CMAKE_FIND_ROOT_PATH |
|
|
NO_CMAKE_FIND_ROOT_PATH]
|
|
)
|
|
|
|
This command is used to find a |SEARCH_XXX_DESC|.
|
|
A cache entry named by ``<VAR>`` is created to store the result
|
|
of this command.
|
|
If the |SEARCH_XXX| is found the result is stored in the variable
|
|
and the search will not be repeated unless the variable is cleared.
|
|
If nothing is found, the result will be
|
|
``<VAR>-NOTFOUND``, and the search will be attempted again the
|
|
next time |FIND_XXX| is invoked with the same variable.
|
|
|
|
Options include:
|
|
|
|
``NAMES``
|
|
Specify one or more possible names for the |SEARCH_XXX|.
|
|
|
|
When using this to specify names with and without a version
|
|
suffix, we recommend specifying the unversioned name first
|
|
so that locally-built packages can be found before those
|
|
provided by distributions.
|
|
|
|
``HINTS``, ``PATHS``
|
|
Specify directories to search in addition to the default locations.
|
|
The ``ENV var`` sub-option reads paths from a system environment
|
|
variable.
|
|
|
|
``PATH_SUFFIXES``
|
|
Specify additional subdirectories to check below each directory
|
|
location otherwise considered.
|
|
|
|
``DOC``
|
|
Specify the documentation string for the ``<VAR>`` cache entry.
|
|
|
|
If ``NO_DEFAULT_PATH`` is specified, then no additional paths are
|
|
added to the search.
|
|
If ``NO_DEFAULT_PATH`` is not specified, the search process is as follows:
|
|
|
|
.. |CMAKE_PREFIX_PATH_XXX_SUBDIR| replace::
|
|
|prefix_XXX_SUBDIR| for each ``<prefix>`` in :variable:`CMAKE_PREFIX_PATH`
|
|
|
|
.. |SYSTEM_ENVIRONMENT_PREFIX_PATH_XXX_SUBDIR| replace::
|
|
|prefix_XXX_SUBDIR| for each ``<prefix>/[s]bin`` in ``PATH``, and
|
|
|entry_XXX_SUBDIR| for other entries in ``PATH``
|
|
|
|
.. |CMAKE_SYSTEM_PREFIX_PATH_XXX_SUBDIR| replace::
|
|
|prefix_XXX_SUBDIR| for each ``<prefix>`` in
|
|
:variable:`CMAKE_SYSTEM_PREFIX_PATH`
|
|
|
|
1. Search paths specified in cmake-specific cache variables.
|
|
These are intended to be used on the command line with a ``-DVAR=value``.
|
|
This can be skipped if ``NO_CMAKE_PATH`` is passed.
|
|
|
|
* |CMAKE_PREFIX_PATH_XXX|
|
|
* |CMAKE_XXX_PATH|
|
|
* |CMAKE_XXX_MAC_PATH|
|
|
|
|
2. Search paths specified in cmake-specific environment variables.
|
|
These are intended to be set in the user's shell configuration.
|
|
This can be skipped if ``NO_CMAKE_ENVIRONMENT_PATH`` is passed.
|
|
|
|
* |CMAKE_PREFIX_PATH_XXX|
|
|
* |CMAKE_XXX_PATH|
|
|
* |CMAKE_XXX_MAC_PATH|
|
|
|
|
3. Search the paths specified by the ``HINTS`` option.
|
|
These should be paths computed by system introspection, such as a
|
|
hint provided by the location of another item already found.
|
|
Hard-coded guesses should be specified with the ``PATHS`` option.
|
|
|
|
4. Search the standard system environment variables.
|
|
This can be skipped if ``NO_SYSTEM_ENVIRONMENT_PATH`` is an argument.
|
|
|
|
* |SYSTEM_ENVIRONMENT_PATH_XXX|
|
|
|
|
5. Search cmake variables defined in the Platform files
|
|
for the current system. This can be skipped if ``NO_CMAKE_SYSTEM_PATH``
|
|
is passed.
|
|
|
|
* |CMAKE_SYSTEM_PREFIX_PATH_XXX|
|
|
* |CMAKE_SYSTEM_XXX_PATH|
|
|
* |CMAKE_SYSTEM_XXX_MAC_PATH|
|
|
|
|
6. Search the paths specified by the PATHS option
|
|
or in the short-hand version of the command.
|
|
These are typically hard-coded guesses.
|
|
|
|
.. |FIND_ARGS_XXX| replace:: <VAR> NAMES name
|
|
|
|
On OS X the :variable:`CMAKE_FIND_FRAMEWORK` and
|
|
:variable:`CMAKE_FIND_APPBUNDLE` variables determine the order of
|
|
preference between Apple-style and unix-style package components.
|
|
|
|
.. include:: FIND_XXX_ROOT.txt
|
|
.. include:: FIND_XXX_ORDER.txt
