how to build in centos7.9?

[xyq-c-cpp]

Download the source code and unzip it, switch the directory to the unzipped code directory,The details are as follows：

tar -zxvf websocketpp-0.8.2.tar.gz
cd websocketpp-0.8.2
mkdir build
cd build
cmake -G "Unix Makefiles" -DCMAKE_C_COMPILER=/usr/local/gcc-5.3.0/bin/gcc -DCMAKE_CXX_COMPILER=/usr/local/gcc-5.3.0/bin/g++ -DCMAKE_INSTALL_PREFIX=/root/websocketpp_install .. -DCMAKE_BUILD_TYPE=Release -DWEBSOCKETPP_BOOST_LIBS=/root/boost_1.72.0_install/lib

make

After the make command, nothing happened.
Should there be some prompts for what happened and what to do when calling cmake? I haven't seen in the documentation how to compile in Centos7.9
