# Backend selection (set BEFORE find_package, or via cmake -D):
# cmake -DNUMPYCPP_STD_ONLY=OFF .. # bitexact (default): SVML + OpenBLAS via dlsym
# cmake -DNUMPYCPP_STD_ONLY=ON .. # std: pure <cmath> + C++ loops, no dlsym
#
# The flag is propagated automatically to every target that links numpycpp:
# bitexact → INTERFACE_LINK_LIBRARIES dl
# std → INTERFACE_COMPILE_DEFINITIONS NUMPYCPP_STD_ONLY

# Non-namespaced + namespaced alias.
# pybind11_add_module users: if the :: target is lost during generation, use
# target_include_directories(mymod PRIVATE ${numpycpp_INCLUDE_DIRS})
