# Default to Release when no build type is given. This is not just about
# optimization: an empty build type leaves NDEBUG undefined, and c4core (vendored
# by rapidyaml) then compiles a debugbreak path calling __builtin_debugtrap,
# which is clang-only and fails to build under GCC. Multi-config generators
# ignore CMAKE_BUILD_TYPE, so skip them rather than set a variable they discard.

# AtomicAndPhysicalConstantsCLib (apc) provides the particle-data functions
# (mass_of / charge_of / anomalous_moment_of) and the named physical constants
# used by the PALS expression evaluator. Its values mirror
# AtomicAndPhysicalConstants.jl so the whole ecosystem shares one set of numbers.
# Pinned to a tag, not main: the reference values in the tests are tied to a
# specific APC release, so an upstream push must not silently change them here.
# apc's version tracks the APC release it mirrors (v0.11.1 = APC v0.11.1).
