devel/py-pybind11 has them in the Python package hierarchy, ie site-packages, also including Python package metadata and a pybind11-config program to assist consumers in finding the headers outside the usual hier(7= ). The scipy build process in meson-python first queries for the pybind11 Pyth= on package, and later during the meson configure process does the header locat= ion get established. devel/pybind11 is harmless to this build process as long as the cmake port/package is not present in the environment. Unfortunately meson will pr= efer to use cmake for dependency detection over pkg-config or other methods like *-config programs, so it is important that, unless a dependency is only mea= nt to be discoverable via cmake, that cmake is not present so meson can use the other methods. It bears repeating that these issues are entirely avoided with environment isolation like poudriere. --=20 You are receiving this mail because: You are the assignee for the bug.=
