Error while building example

I was able to install the tool successfully (I hope) using the instructions given. However while checking out examples, I faced the following issue:

(base) [om@darkknight build]$ cmake .. -DVIENNAPS_BUILD_EXAMPLES=ON

Is there a documentation on how to use the tool?

It appears that there may be compatibility issues with your compiler and the C++17 standard. Could you please verify if you are using a C++17 compiler? Additionally, providing more details about your system setup would be helpful for further diagnosis.

While there is some documentation available (ViennaPS Doc), it is currently a work in progress and may not cover all aspects comprehensively yet.
