# numpycpp -- header-only C++ numpy API library.

# 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})
