CMake version mismatched for Dawn

[goldragoon]

I tried to build examples inside of the docker image like : bash ./build.sh -webgpu_native_examples

But build procedure suddenly stops by below error :

-- Dawn: using SPIRV-Headers at /webgpu-native-examples/external/dawn/dawn/third_party/vulkan-deps/spirv-headers/src
-- Dawn: using SPIRV-Tools at /webgpu-native-examples/external/dawn/dawn/third_party/vulkan-deps/spirv-tools/src
CMake Error at external/dawn/dawn/third_party/vulkan-deps/spirv-tools/src/CMakeLists.txt:15 (cmake_minimum_required):  CMake 3.17.2 or higher is required.  You are running version 3.16.3

I think command for installing more recent version of CMake is required for the docker file

like (it works for me!) :

Hello goldragoon,

thanks for reporting this issue and for providing the fix for the cmake version issue. I updated the docker file in this commit. The latest Dawn version seems to need a recent cmake version, good that the issue is resolved now.

With best regards, Sam
