    # NOTE: we need to install the dependencies in install-deps because for those ones using the cmake config file,
    # some of their dependencies are linked with hard-coded paths to the place where they where installed when said
    # dependency was built. E.g. Alembic depends on openExr and the AlembicConfig.cmake contains hard-coded links to
    # the path /home/travis/build/alicevision/AliceVisionDependencies/install-deps, which was where openExr was installed
    # when Alembic was built (see AliceVisionDependencies repository).
