LIBRARY DESTINATION ${Python_SITELIB} |
CMake FindPython seems to populate Python_SITELIB to an absolute system path.
ROS builds are thus failing with eg. https://build.ros2.org/job/Kdev__nanoeigenpy__ubuntu_noble_amd64/4/console:
PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.12/dist-packages/nanoeigenpy.pyi'
CMake Error at cmake_install.cmake:89 (file):
file INSTALL cannot copy file
"/tmp/ws/build_isolated/nanoeigenpy/lib/nanoeigenpy.cpython-312-x86_64-linux-gnu.so"
to
"/usr/local/lib/python3.12/dist-packages/nanoeigenpy.cpython-312-x86_64-linux-gnu.so":
Permission denied.
Same issue on Nix side, where this is patched: https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/python-modules/nanoeigenpy/default.nix#L38
PermissionError: [Errno 13] Permission denied:
'/nix/store/…-python3-3.12.9/lib/python3.12/site-packages/nanoeigenpy.pyi'
That CMake variable is initialized from sysconfig.get_path('purelib'), but in other projects we instead use Path(sysconfig.get_path('purelib')).relative_to(sysconfig.get_path('data')) to fix this issue, ref. https://github.com/jrl-umi3218/jrl-cmakemodules/blob/c815b3ba45fa8b7cf4b7a21b69b26ad0bc04fd5c/python.cmake#L310C62-L310C137
