Subject: [PATCH] cmake: Add support for custom protoc executable via
 OR_TOOLS_PROTOC_EXECUTABLE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Allow users to specify a custom protoc executable by setting the
OR_TOOLS_PROTOC_EXECUTABLE variable, which takes precedence over
the default cross-compilation and system protoc detection logic.
