Which cmake version to use? Can't compile/install.

[russelljjarvis]

Hi there,

I am trying to compile Nest-gpu to experiment with calling it from Julia-lang with

https://github.com/JuliaInterop/CxxWrap.jl

However I am finding that I can not basically install nest-gpu. I suspect I am just using the wrong compiler versions.

Which cmake versions have you had success with?

@pop-os:~/git/nest-gpu$ cmake -DCMAKE_INSTALL_PREFIX:PATH=`pwd` .
