macOS got all the way through this time: the synthesised SDK path satisfied OBS's version check, the sub-build configured, and libobs built and installed -- libobs.framework with its headers, libobsConfig.cmake and libobsTargets.cmake all landed. Then the install failed on the NEXT subproject: file INSTALL cannot find ".../UI/obs-frontend-api/obs-frontend-api.dylib": No such file or directory Installing from the top-level build directory walks every subproject's cmake_install.cmake, and obs-frontend-api is a target this build deliberately never builds -- that is the whole point of dropping Qt. Pointing --install at the libobs subdirectory installs exactly what find_package(libobs) needs and nothing else.
