# Test goal: Initial build with close-to-default settings that always needs to pass before follow-up CI stages run
# Test intents (should change rarely and conservatively):
#   OS: Ubuntu oldest supported
#   Compiler: Clang
#   Build type: Debug
#   CMake: oldest supported
#   GPU: no
#   SIMD: no
#   Scope: configure, build, unit tests
# Test implementation choices (free to change as needed):
#   OS: Ubuntu 20.04
#   Compiler: Clang 12
#   FFT: FFTW3
#   Parallelism nt/ntomp: 4/2
