今日在安装MariaDB的时候始终提示如下错误，但是我已经安装了libaio-devel库：
CMake Error at cmake/build_configurations/mysql_release.cmake:128 (MESSAGE):
aio is required on Linux, you need to install the required library:
Debian/Ubuntu: apt-get install libaio-dev
RedHat/Fedora/Oracle Linux: yum install libaio-devel
SuSE: zypper install libaio-devel
If you really do not want it, pass -DIGNORE_AIO_CHECK to cmake.
搜寻各种解决方案后才知道因为刚开始第一次执行cmake的时候就产生了CMakeCache.txt，这个时候我并没有安装libaio-devel库，然后继续安装依赖库后再执行cmake其实读取的依然是前面生成的cache文件，导致cmake判断libaio-devel一直未被安装。因此只要我们rm删除CMakeCache.txt文件后重新执行cmake命令既可以解决此问题.
