 # This variable controls which dependency is resolved by the pass-through
 # target 'cld2_platform_impl', and allows the embedder to choose which
 # kind of CLD2 support is required at build time:
 #
 # - If the value is 'static', then the cld2_platform_impl target will depend
 #   upon the cld2_static target
 # - If the value is 'dynamic', then the cld2_platform_impl target will
 #   depend upon the cld2_dynamic target.
 #
 # High-level targets for Chromium unit tests hard-code a dependency upon
 # cld2_static because doing so makes sense for use cases that aren't
 # affected by the loading of language detection data; however, most other
 # targets (e.g. the final executables and interactive UI tests) should be
 # linked against whatever the embedder needs.
 #
 # Maintainers:
 # This value may be reasonably tweaked on a per-platform basis.
 # Don't forget to update this file as well to match:
 #   components/translate/content/browser/browser_cld_utils.cc
 #   components/translate/content/renderer/renderer_cld_utils.cc
