SU2-feature_adap branch ninja compile error

[MSLEE-AERO]

Hello, I'm Minsul.

I am struggling to compile SU2-feature_adap branch.

My purpose for using the branch is mesh adaptation.

But the problem is that whenever I command ./meson.py build,

It shows the error message: meson.build:1:0: ERROR: Value "c++11" for combo option is not one of the choices. Possible choices are: "none", "c++98", "c++03", "gnu++98", "gnu++03".

So I tried to edit meson.build file. not c++11 but c++03 or c++98.

But I get to know that It is necessary of c++11 to compile SU2_CFD.

Is there any one else who can help me solve this problem?

Thank you.
