I looked in the problem file (~/.cache/yay/gazebo/src/gazebo-classic-gazebo11_11.14.0/build/gazebo/msgs/CMakeFiles/gazebo_msgs.dir/build.make):

Seems to be missing a command protoc before --plugin=, but can't understand why...

Got the same problem, and use sed as a workround to build successfully.

I have the same issue. PROTOBUF_PROTOC_EXECUTABLE is not set for some reason. I edited the cmake invocation in PKGBUILD, just hardcoding the path.

cmake .. -DCMAKE_BUILD_TYPE="Release" \
         -DCMAKE_INSTALL_PREFIX="/usr" \
         -DCMAKE_INSTALL_LIBDIR="lib" \
         -DPROTOBUF_PROTOC_EXECUTABLE="/usr/bin/protoc"

Seems to work around the real issue. At least gazebo compiles now.

Thanks for the workaround @kvkoskin!
