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.

38 # is currently off by default while the specification is provisional, as it may
39 # change.
