error: narrowing conversion of ‘***********’ from ‘unsigned int’ to ‘int’ [-Wnarrowing]

hello: I'm trying to build rpc library from source.

When executing command: cmake --build . --target install

show err :

/home/fastdds/RPC-master/examples/C++/rpcdds/c++11Types/RTPSCalculator/CalculatorDDSProtocol.cxx:131:22: error: narrowing conversion of ‘3418803882’ from ‘unsigned int’ to ‘int’ [-Wnarrowing]

I add the following words in my cmakelists.txt to avoid narrow conversion.

add_compile_options(-Wno-narrowing)
