Summary:                    PROTOBUF_GENERATE_CPP does not add
__attribute__(const|pure) to the suitable, generated, functions.
Description: 
FindProtobuf.cmake makes the PROTOBUF_GENERATE_CPP macro available. If I attempt
to add_compile_options(-Wall -Wsuggest-attribute=pure -Wsuggest-attribute=const)
I note that the generated code has not had these optimisation options applied.

Steps to Reproduce: 
1. find_package(ProtoBuf)
2. add_compile_options(-Wall -Wsuggest-attribute=pure -Wsuggest-attribute=const)
3. PROTOBUF_GENERATE_CPP(PROTO_SRCS PROTO_HDRS ${PROTOCOLS})
4. add_library(${PROJECT_NAME} OBJECT ${PROTO_SRCS} ${PROTO_HDRS})


Additional Information: 
Surely modifying the generator to add these attribute to the function generator
should be pretty easy.
