FindPSXSDK
-----------

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
