Thanks for the fix.

See suggested change.

Not sure why opentelemetry-proto.cmake was not formatted in my previous change, as CI was ok on format.

Maybe we should use cmake-format -i $($FIND -name 'CMakeLists.txt' -print -o -name '*.cmake' -print -o -name '*.cmake.in' -print) in tools/format.sh. (Add -o between rules.)
