CMakeLists.txt有点问题

[heheda123123]

把workspace提交到xmake-repo了 https://github.com/xmake-io/xmake-repo/pull/2104

但是现在的CMakeLists.txt写得有点问题，会导致ubuntu的测试通不过，需要patch

在我的机器上没测出问题，能把报错信息发一下吗

需要权限，采用sudo make install 即可

[heheda123123]

有两个问题
1 现在的CMakeLists.txt是直接指定的绝对路径，这导致用户没法自定义安装路径，需要像我最上面发的截图那样删掉前缀 2 CMAKE_INSTALL_PREFIX 有默认值，在linux是/usr/local，在win是 C:/Program Files。所以不需要现在这样判断，install的时候指定相对路径即可

很酷！我已经改好了。
