include(BundleUtilities) # After the relevant targets, support files, as well as plugins have already been installed into the bundle structure, # the bundle must still be made standalone by copying the required frameworks and making them position-independent. # This is generally called "fixing up" the bundle. # # Principally there are two ways to do that: Qt's official macdeployqt tool, and CMake's BundleUtilities. # # Some frameworks, in particular QtWebEngineCore, come with nested bundles. In order for them to work correctly, the Frameworks directory # from the main bundle must be symlinked into the nested bundle, otherwise dependencies cannot be resolved. # Neither macdeployqt (shockingly) nor BundleUtilities can handle this properly. The former simply ignores nested bundles and thus # does not fix them up at all. The latter scans for additional binaries and tries fixing them up, but there is no way to inject # creation of the Frameworks symlink between the copy and the fixup steps. # # The working solution implemented here is to first run macdeployqt (which also handles some Qt-specific quirks), then symlink Frameworks # into the nested bundles (if any), then use BundleUtilities to perform the remaining fixups and verify the bundle. # Since we're in the install phase, DESTDIR might be set set(BUNDLE_PATH "$ENV{DESTDIR}@BUNDLE_PATH@") set(DMG_PATH "$ENV{DESTDIR}@DMG_PATH@") # First, use Qt's official tool, macdeployqt, for deploying the needed Qt Frameworks into the bundle message(STATUS "Deploying Qt Frameworks in bundle \"${BUNDLE_PATH}\"") execute_process( # Don't deploy plugins - we've already installed the selection relevant for our target!
