| # 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. |
