C++ Purecap Cross compile

Hi All,

I'm wondering what the best way to compile purecap c++  applications is?

Currently I'm running Android nano on the development board following the instructions in the user guide. I have successfully compiled c applications using the musl c library but now have a dependency on a c++ application. 

I can't find a purecap libc++ within the morello_workspace. Is there a library available?
