Known build issues

LUMI

When building DLA-Future for the GPU partition of LUMI (https://www.lumi-supercomputer.eu/) you may need to specify which GCC toolchain that HIP will use with the CMake variable

CMAKE_HIP_FLAGS=--gcc-toolchain=/opt/cray/pe/gcc/11.2.0/snos

Otherwise you may end up using the default system installation of GCC which doesn't have e.g. <filesystem> support.
