+ENV PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/lib64/pkgconfig:/usr/lib64/pkgconfig
+ENV PATH=/usr/local/bin:${PATH}
+# ```
+
+# #### Abseil
+
+# Rocky Linux 9 includes a package for Abseil, unfortunately, this package is
+# incomplete, as it lacks the CMake support files for it. We need to compile
+# Abseiil from source.
+
+# :warning: By default, Abseil's ABI changes depending on whether it is used
+# with C++ >= 17 enabled or not. Installing Abseil with the default
+# configuration is error-prone, unless you can guarantee that all the code using
+# Abseil (gRPC, google-cloud-cpp, your own code, etc.) is compiled with the same
+# C++ version. We recommend that you switch the default configuration to pin
+# Abseil's ABI to the version used at compile time. In Rocky Linux 9 the
+# compiler defaults to C++17. Therefore, we change `absl/base/options.h` to
+# **always** use `std::any`, `std::string_view`, and `std::variant`. See
+# [abseil/abseil-cpp#696] for more information.
+
+# ```bash
+WORKDIR /var/tmp/build/abseil-cpp
+RUN curl -sSL https://github.com/abseil/abseil-cpp/archive/20220623.1.tar.gz | \
+    tar -xzf - --strip-components=1 && \

+# ```
+
+# #### Protobuf
+
+# Rocky Linux ships with Protobuf 3.14.x.  Some of the libraries in
+# `google-cloud-cpp` require Protobuf >= 3.15.8.  For simplicity, we will just
+# install Protobuf (and any downstream packages) from source.

+# #### gRPC
+
+# We also need a version of gRPC that is recent enough to support the Google
+# Cloud Platform proto files. Note that gRPC overrides the default C++ standard
+# version to C++14, we need to configure it to use the platform's default. We
