This seems to be an upstream issue: https://github.com/libexpat/libexpat/issues/501
With that said, it doesn't seem like an upstream fix is likely any time soon, as is suggested by this comment by one of the members of the `libexpat` GitHub team on this NixOS pull request addressing this issue: https://github.com/NixOS/nixpkgs/pull/128997#issuecomment-873137856 NixOS seems to have a custom packaging setup, so the fix above is most likely not applicable. ** Bug watch added: github.com/libexpat/libexpat/issues #501 https://github.com/libexpat/libexpat/issues/501 ** Description changed: Using the package provided by Ubuntu Impish results in the following CMake configuration error when trying to build OpenColorIO: ``` […] CMake Error in src/OpenColorIO/CMakeLists.txt: - Imported target "expat::expat" includes non-existent path + Imported target "expat::expat" includes non-existent path - "/usr/lib/include" + "/usr/lib/include" - in its INTERFACE_INCLUDE_DIRECTORIES.

[…] ``` This wasn't an issue in Ubuntu Hirsute as far as I can recall and is not an issue when using the ASWF-provided packages — CMake flag `-DOCIO_INSTALL_EXT_PACKAGES=ALL`. A patch is attached that allows OpenColorIO to build using system-provided packages. - Related ticket over on the OpenColorIO GitHub repository: - https://github.com/AcademySoftwareFoundation/OpenColorIO/issues/1415 + Further information in the related ticket in the OpenColorIO repository: + https://github.com/AcademySoftwareFoundation/OpenColorIO/issues/1415#issuecomment-1003826550 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1956202 Title: `libexpat1-dev` CMake configuration error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/expat/+bug/1956202/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
