Install gRPC for PHP failed

I want to install gRPC to ubuntu 16.04 for PHP. I followed the official documentation: https://cloud.google.com/php/grpc#build-from-source

When I run this command:

sudo make install

I am getting this error:

Installing via 'make' is no longer supported. Use cmake or bazel instead. Please consult BUILDING.md to get more information.

How can I use cmake or bazel to install? Please, help me.

Note: I can not user PECL. PECL's website is blocked by my hosting provider. That's why I need to build it manually.
