#60 Qomo Linux 4.9上无法编译安装Qterm 0.5.12
在这里发过一个贴子：
http://www.linux-ren.org/forum.php?mod=viewthread&tid=56150&page=1#pid368004
我copy内容如下。
执行的命令：
cd qterm-0.5.12
mkdir build
cd build
cmake ..
这时屏幕输出内容看到报错如下：

暂时先挪走 /usr/share/apps/cmake/modules/FindQt4.cmake，重新执行cmake就OK了，但是在执行make时又报错如下：

没见到过这样的错误，只能尝试排除法：
编辑 qterm/CMakeLists.txt,
find_package(Qt4 4.5.0 REQUIRED)
-> find_package(Qt4)
