Error while make process

Hi I'm having this error while making process

[ 6%] Building CXX object opt/cpr/cpr/CMakeFiles/cpr.dir/auth.cpp.o [ 12%] Building CXX object opt/cpr/cpr/CMakeFiles/cpr.dir/cookies.cpp.o [ 18%] Building CXX object opt/cpr/cpr/CMakeFiles/cpr.dir/cprtypes.cpp.o [ 25%] Building CXX object opt/cpr/cpr/CMakeFiles/cpr.dir/digest.cpp.o [ 31%] Building CXX object opt/cpr/cpr/CMakeFiles/cpr.dir/error.cpp.o /root/cpr-example/opt/cpr/cpr/error.cpp: In static member function ‘static cpr::ErrorCode cpr::Error::getErrorCodeForCurlError(int32_t)’: /root/cpr-example/opt/cpr/cpr/error.cpp:41:9: error: duplicate case value 41 | case CURLE_SSL_CACERT: | ^~~~ /root/cpr-example/opt/cpr/cpr/error.cpp:25:9: note: previously used here 25 | case CURLE_PEER_FAILED_VERIFICATION: | ^~~~ make[2]: *** [opt/cpr/cpr/CMakeFiles/cpr.dir/build.make:115: opt/cpr/cpr/CMakeFiles/cpr.dir/error.cpp.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:180: opt/cpr/cpr/CMakeFiles/cpr.dir/all] Error 2 make: *** [Makefile:84: all] Error 2

cmake process is completely fine but when I try to build by issuing make I got the above error
