A possible approche for particle solvers. Instead of testing if we can compile different solver with `cmakeFlags` we could simply add more species with the different solvers activated.

Please check https://github.com/ComputationalRadiationPhysics/picongpu/pull/1579 too. But most likely the issue is not present in modern nvcc anymore.

Thanks for pointing us to the issue. Currently, I do not think that we can handle the issue in our code base. The issue was triggered by a user-defined operator...

@krzikalla Is the error triggered by a operator definition within alpaka or is the operator defined in your code base? I figured out that the compile issue is always showing...

@q-p Thanks for the information. Currently, I do not see how we can work around the compiler bug. I think we must wait until llvm is fixing the issue.
