scons: *** No SConstruct file found解决

            编译最新版本的的jsoncpp,执行指令scons platform=linux-gcc，编译出错

scons: *** No SConstruct file found.
File "/usr/lib/scons/SCons/Script/Main.py", line 940, in _main

解决

        最新版本的jsoncpp已经不支持scons进行编译，采用CMake。scons依赖源码提供的README.txt SConstruct  version等文件，所以才会出现提示如上的错误
