+-------
+
+Finds the React Physics 3D library.
+
+Imported Targets
+^^^^^^^^^^^^^^^^
+
+This module provides the following imported targets, if found:
+
+``Rp3d::Rp3d``
+  The React Physics 3D library
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+This will define the following variables:
+
+``Rp3d_FOUND``
+  True if the system has the React Physics 3D library.
+``Rp3d_VERSION``
+  The version of the React Physics 3D library which was found.
+``Rp3d_INCLUDE_DIRS``
+  Include directories needed to use React Physics 3D.
+``Rp3d_LIBRARIES``
+  Libraries needed to link to React Physics 3D.
+
+Cache Variables
+^^^^^^^^^^^^^^^
+
+The following cache variables may also be set:
+
+``Rp3d_INCLUDE_DIR``
+  The directory containing ``reactphysics3d.h``.
+``Rp3d_LIBRARY``
+  The path to the React Physics 3D library.
