 # The option below allows building the ICD Loader library as a shared library
 # (ON, default) or a static library (OFF).
 #
 # Khronos OpenCL Working Group strongly recommends building and using the ICD
 # loader as a shared library due to the following benefits:
 #
 # 1. The shared library can be updated independent of the application. This
 #    allows releasing new fixes and features in the ICD loader without updating
 #    the application.
 #
 #    In rare cases when there are backward-incompatible changes to the ICD
 #    loader (due to platform requirements, for instance), using a shared
 #    library allows updating the library to make the transition seamless to
 #    installed applications.
 #
 # 2. On platforms that require the ICD mechanism there are multiple vendors
 #    shipping their OpenCL implementations. The vendor installers collaborate
 #    to make sure that the installed ICD shared library version is suitable for
 #    working with all vendor implementations installed on the system.
 #
 #    If applications statically link to ICD Loader then that version of the ICD
 #    loader may not work with one or more installed vendor implementations.
 #
 # Using the OpenCL ICD loader as a static library is NOT recommended for
 # end-user installations in general. However in some controlled environments it
 # may be useful to simplify the build and distribution of the application. E.g.
 # in test farms, or in cases where the end-user system configs are known in
 # advance. Use it with discretion.
