   7 # The option below allows building the ICD Loader library as a shared library
   8 # (ON, default) or a static library (OFF).
   9 #
  10 # Khronos OpenCL Working Group strongly recommends building and using the ICD
  11 # loader as a shared library due to the following benefits:
  12 #
  13 # 1. The shared library can be updated independent of the application. This
  14 #    allows releasing new fixes and features in the ICD loader without updating
  15 #    the application.
  16 #
  17 #    In rare cases when there are backward-incompatible changes to the ICD
  18 #    loader (due to platform requirements, for instance), using a shared
  19 #    library allows updating the library to make the transition seamless to
  20 #    installed applications.
  21 #
  22 # 2. On platforms that require the ICD mechanism there are multiple vendors
  23 #    shipping their OpenCL implementations. The vendor installers collaborate
  24 #    to make sure that the installed ICD shared library version is suitable for
  25 #    working with all vendor implementations installed on the system.
  26 #
  27 #    If applications statically link to ICD Loader then that version of the ICD
  28 #    loader may not work with one or more installed vendor implementations.
  29 #
  30 # Using the OpenCL ICD loader as a static library is NOT recommended for
  31 # end-user installations in general. However in some controlled environments it
  32 # may be useful to simplify the build and distribution of the application. E.g.
  33 # in test farms, or in cases where the end-user system configs are known in
  34 # advance. Use it with discretion.
  35 option (BUILD_SHARED_LIBS "Build shared libs" ON)
  36
  37 # This option enables support for OpenCL 3.0 Provisional in the ICD loader.  It
  38 # is currently off by default while the specification is provisional, as it may
  39 # change.
