🍎 Mac Qt6 .dmg

[m-kuhn]

Description

Creates macos installers (dmg), based on Qt6/vcpkg for desktop components

• It provides QGIS, qgis_process, qgis_bench and a few executable binaries
• The package is created for master, pull requests and releases
• It creates two builds, one for x64 (intel) and one for arm64 (M) processors
• It simplifies a lot of cmake code by not building frameworks. If there is a good reason to reintroduce frameworks, I am happy to discuss how to deal with specific use cases for which they are currently used.
• It separates the Python_SITEARCH directory with an absolute system path (where site-packages is installed on the system) from a new variable QGIS_PYTHON_INSTALL_DIR with relative variable where our python bindings will be installed to (which can be the same path as Python_SITEARCH if the prefix provided through CMAKE_INSTALL_PREFIX and/or DESTDIR matches)
• It completely removed CMAKE_INSTALL_DIR from cmake code in install directives, to allow for installation on relative paths
• It does not include QGIS server, if you want to run QGIS server on macos, there are homebrew, conda and other options
• This removes the current mac bundles (the dependencies in there are outdated)
• It separates building the application (for development/debugging) from bundling. The macos bundle is only created at bundling time. For debugging, no libraries are copied into the build path.
• For creating an app and fixing rpath, macdeployqt is used (only minimal usage within cmake)
• For creating a shiny dmg, create-dmg is used
• No notarisation or code signing is done (yet)

Creating the dmg on x64 github action runners (macos-13) randomly fails because of "resource busy" in hdiutil. There is not much we can do but retry until we succeed -- which can eventually take a very long time.

Creating the dmg on x64 github action runners (macos-13) randomly fails because of "resource busy" in hdiutil. There is not much we can do but retry until we succeed -- which can eventually take a very long time.

Should we just disable these then? (At least it's only the legacy build)

Possibly, I'm trying to create a zip or a universal app. Last resort would be killing x64
