求助：CentOS6编译安装fcitx4.1.2出现问题？

cmake .. -DCMAKE_INSTALL_PREFIX=/usr

执行以上命令时出现以下错误：

-- Could NOT find Libkvm (missing: LIBKVM_INCLUDE_DIR LIBKVM_FOUND)
-- checking for module 'dbus-1 >= 1.1.0'
-- package 'dbus-1 >= 1.1.0' not found
-- checking for module 'opencc >= 0.1.1'
-- package 'opencc >= 0.1.1' not found
-- Configuring done
-- Generating done
-- Build files have been written to: /usr/src/fcitx-4.1.2/build

这是少什么包呀，那位大哥知道的告诉下……
谢谢
