Message : D3D: Make possible to build angle without D3D11 A few files inside the D3D11 tree are used by D3D9 and WGL backends. We add these files to the build system even when D3D11 is disabled. Also, we fix the use the of ANGLE_DEFAULT_D3D11 symbol. Bug: angleproject:4839 Change-Id: I981f4bfc60d973c02549caa737c5aed5ccf31282 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2298143 Reviewed-by: Geoff Lang <geofflang@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Geoff Lang <geofflang@chromium.org>
