+FindJsonCpp
+-----------
+
+Find JsonCpp includes and library.
+
+Imported Targets
+^^^^^^^^^^^^^^^^
+
+An :ref:`imported target <Imported targets>` named
+``JsonCpp::JsonCpp`` is provided if JsonCpp has been found.
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This module defines the following variables:
+
+``JsonCpp_FOUND``
+ True if JsonCpp was found, false otherwise.
+``JsonCpp_INCLUDE_DIRS``
+ Include directories needed to include JsonCpp headers.
+``JsonCpp_LIBRARIES``
+ Libraries needed to link to JsonCpp.
+``JsonCpp_VERSION_STRING``
+ The version of JsonCpp found.
+ May not be set for JsonCpp versions prior to 1.0.
+``JsonCpp_VERSION_MAJOR``
+ The major version of JsonCpp.
+``JsonCpp_VERSION_MINOR``
+ The minor version of JsonCpp.
+``JsonCpp_VERSION_PATCH``
+ The patch version of JsonCpp.
+
+Cache Variables
+^^^^^^^^^^^^^^^
+
+This module uses the following cache variables:
+
+``JsonCpp_LIBRARY``
+ The location of the JsonCpp library file.
+``JsonCpp_INCLUDE_DIR``
+ The location of the JsonCpp include directory containing ``json/json.h``.
+
+The cache variables should not be used by project code.
+They may be set by end users to point at JsonCpp components.
