./Tools/Scripts/build-webkit --gtk --release --cmakeargs="-DUSE_GTK4=ON" ... -- Checking for module 'gtk4' -- Found gtk4, version 3.98.3 -- Checking for module 'gtk4-unix-print' -- Found gtk4-unix-print, version 3.98.3 CMake Error at /usr/share/cmake-3.15/Modules/FindPackageHandleStandardArgs.cmake:137 (message): Could NOT find GTK (missing: GTK_VERSION_OK) (Required is at least version "3.98.4")
At this moment, working on GTK4 requires to use gtk from git master and update often, so I think it's better to use jhbuild.
I don't mind updating the SDK whenever you ask it, FWIW.
Also, this is documented now: http://trac.webkit.org/browser/webkit/trunk/Tools/buildstream/README.rst In case anybody would like to try, feedback is always welcome :)
