在Red Hat Enterprise Linux Server release 5.7 上用源码安装MySQL-5.6.23时，遇到了" remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel."错误，如下所示
[root@DB-Server mysql-5.6.23]# cmake ./ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data

按照错误提示，Debian/Ubuntu下需要安装libncurses5-dev；Redhat下需要安装ncurses-devel ，检查是否安装了ncurses包，如下所示，已经安装了ncurses-5.5-24.20060715，但是缺少ncurses-devel包。

安装了ncurses-devel包后，删除CMakeCache.txt，然后重新编译，编译成功，问题解决！
