[abeltrano]

Type

• Bug fix
• Feature addition
• Feature update
• Documentation
• Build Infrastructure

Side Effects

• Breaking change
• Non-functional change

Goals

• Attempt to enable building for Windows ARM64 architecture, specifically the ARM64EC ABI.

Technical Details

• Replace use of standard gRPC CMake targets with "unsecure" ones, which do not link SSL dependents.
• Add CMake configure preset for building ARM64 on Windows.

Test Results

• Cross-compile build for ARM64 on Windows with Debug flavor succeeded.

Reviewer Focus

• None

Future Work

• Using the insecure targets is not desirable. While this framework is intended mostly for test environments where security may not be required or important, having a secure transport should be an option for corner cases. So, we need to figure out a workaround to enable use of the normal targets that support SSL.
• Enable use of SSL in gRPC transport #95

Checklist

• Build target all compiles cleanly.
• clang-format and clang-tidy deltas produced no new output.
• Newly added functions include doxygen-style comment block.
