After installation of sci-libs/caffe2, if I run the following command: $ cmake --find-package -DNAME=Torch -DCOMPILER_ID=GNU -DLANGUAGE=C -DMODE=COMPILE it outputs: -I/usr/include -I/usr/include/torch/csrc/api/include However, the second directory does not exist, as current ebuild moves torch headers from /usr/include/torch to /usr/lib/python3.11/site-packages/torch/include/ It causes issues with compilation of https://github.com/intel/intel-extension-for-pytorch, as it uses common CMake logic (find_package, target_link_libraries) to link with pytorch. I suggest to store headers in /usr/include/torch, and have a symlink in /usr/lib/python3.11/site-packages/torch/include/, this covers multiple scenarios and allows to build intel-extension-for-pytorch (with minor patches, unrelated to Gentoo).
