# generate reduced test matrix
# required variables (space separated lists):
#   PIC_INPUTS - Path to examples relative to share/picongpu.
#                If input is 'pmacc' the folder will be ignored and tests for pmacc will be generated.
#                e.g.
#                    "examples" starts one gitlab job per directory in `examples/*`
#                    "examples/" compile all directories in `examples/*` within one gitlab job
#                    "examples/KelvinHelmholtz" compile all cases within one gitlab job
