【解决方法】

分别执行如下命令，安装devtoolset-10工具集：

yum install -y centos-release-scl

yum install -y devtoolset-10

scl enable devtoolset-10 bash

再次执行cmake .. -DBUILD_CONFIG=mysql_release -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql/data -DWITH_BOOST=/home/mysql-8.0.24/boost/boost_1_73_0 即可正常编译通过
