Full listing of cmake options?

[VictorEijkhout]

This page is a bit minimal:
https://nekrs.readthedocs.io/en/latest/quickstart.html#building-nekrs

Is there a full listing of CMake options?

[yslan]

You can use this to get all CMake option:

cmake -LAH .

For cache variable used in the project, it might need to configure first, which is doable via:

cmake -S . -B _probe
cmake -LAH _probe

We should document this.
Before that, here is a list from CMakeList.txt.

set(ENABLE_AMGX OFF CACHE BOOL "Enable NVIDIA AMGX support")
set(ENABLE_HYPRE_GPU ON CACHE BOOL "Enable HYPRE GPU support")
set(NEKRS_GPU_MPI OFF CACHE BOOL "Enable GPU aware MPI")
set(ENABLE_CVODE OFF CACHE BOOL "Enable CVODE support")
set(ENABLE_ADIOS ON CACHE BOOL "Enable ADIOS support")
set(ADIOS2_INSTALL_DIR "" CACHE STRING "ADIOS install directory")
set(NEKRS_BUILD_FLOAT ON CACHE BOOL "Build dfloat = float version")

set(ENABLE_CPPTRACE OFF CACHE BOOL "Enable cpptrace for stack tracing")

I would really appreciate a web page.

The listing you give from the cmakelists is incomplete: it doesn't mention blas & cuda options.

Is this issue abandoned? I'm getting increasing requests for this package, so some guidance wrt an optimized installation would be nice.

For good performance, no special flags are needed.

[VictorEijkhout]

You have a flag for optimized blas/lapack.

[stgeke]

There is no need to use an external or optimized BLAS/LAPACK implementation. These libraries are not used during the actual computation, so they have no impact on performance.
