The `find_package_handle_standard_args(FOUND_VAR)` is deprecated as of CMake 3.3 and both the `<PackageName>_FOUND` and the upper-cased `<PACKAGE_NAME>_FOUND` are set with or without using this option. Additionally, find modules and docs are also synced with this to make it clearer.

FindXercesC
|
|
-----------
|

|
|
Imported targets
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
.. versionadded:: 3.5
|
|
|
|
This module defines the following :prop_tgt:`IMPORTED` targets:
|
|
|
|
``XercesC::XercesC``
|
|
The Xerces-C++ ``xerces-c`` library, if found.
|
|
|
|
Result variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module will set the following variables in your project:
|
|
|
|
``XercesC_FOUND``
|
|
true if the Xerces headers and libraries were found
|
|
``XercesC_VERSION``
|
|
Xerces release version
|
|
``XercesC_INCLUDE_DIRS``
|
|
the directory containing the Xerces headers
|
|
``XercesC_LIBRARIES``
|
|
Xerces libraries to be linked
|
|
|
|
Cache variables
|
|
^^^^^^^^^^^^^^^
|
|
|
|
The following cache variables may also be set:
|
|
|
|
``XercesC_INCLUDE_DIR``
|
|
the directory containing the Xerces headers
|
|
``XercesC_LIBRARY``
|
|
the Xerces library
|
|
|
|
.. versionadded:: 3.4
|
|
Debug and Release variants are found separately.
