+-----------
+
+Find PSXSDK (an open source software development kit for the original
+Sony PlayStation) libraries and header files.
+
+Imported targets
+^^^^^^^^^^^^^^^^
+
+This module defines the following :prop_tgt:`IMPORTED` targets:
+
+  ``PSXSDK::PSXSDK``,
+  The PSXSDK `psx` library, if found.
+
+Result variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project:
+
+``PSXSDK_FOUND``
+  true if PSXSDK libraries and header files were found.
+``PSXSDK_VERSION``
+  PSXSDK release version
+``PSXSDK_INCLUDE_DIRS``
+  the directory containing the PSXSDK headers; note
+  ``PSXSDK_INCLUDE_DIRS`` is also required
+``PSXSDK_LIBRARIES``
+  PSXSDK libraries to be linked; note ``PSXSDK_LIBRARIES`` is also
+  required
