ROBAST软件安装问题

[Ye2019]

我在尝试安装ROBAST软件，是一个linux下的照明光学软件，http://robast.github.io/user_guide.html#，这个软件依赖于root.cern包，https://root.cern/.
现在root可以呈现出想要的效果，但是测试robast，就会提示找不到头文件。我怀疑是路径问题。

ROBAST depends on only ROOT libraries. If you have already installed ROOT on your Linux or Mac, please check whether environmental variables ROOTSYS, LD_LIBRARY_PATH, and PATH are properly set in your shell. If ROOTSYS points to /usr/local/root for example, LD_LIBRARY_PATH and PATH are usually set to /usr/local/root/lib and /usr/local/root/bin, respectively.

这一段提示里，ROOTSYS 指的是什么，以及
In addition, you must add the ROBAST include directory to the ROOT search path. Add the following line to your existing $HOME/.rootlogon.C

gInterpreter->AddIncludePath("YOUR_ROBAST_DIRECTORY/include");

这个，应该加在哪里？
求助，孩子装了一个星期了。。。

一个星期啊，翻字典也该查明白了吧？
ROOTSYS是environmental variables，那句话让你检查ROOTSYS, LD_LIBRARY_PATH,和 PATH 配置对了没
下面这两句让你改个文件，文件里加上下面那一行
In addition, you must add the ROBAST include directory to the ROOT search path.

Add the following line to your existing $HOME/.rootlogon.C
