Believe GTK has branched so this can potentially land.

This opens up GTK to build with hidden visibility turned on.

Yes, Carlos has created our 2.32.x release branch some days ago.

cmake_minimum_required(VERSION 3.10) is also present in subprojects, such as Source/WTF/CMakeLists.txt

Good catch forgot about the AppleWin build doing that.

Great idea, similar mistakes were made in the past too

This broke compilation on Ubuntu 18.04 as it comes with cmake 3.10. I'd point to the Ububntu 1804 build bot but has been in a bad state for a different reason (https://build.webkit.org/#/builders/71).

Is it possible to keep the min cmake version at 3.10 while Ubuntu 1804 is an officially supported LTS?

[Michael Catanzaro]

Hi Yury, support for Ubuntu 18.04's toolchain ends in April according to https://trac.webkit.org/wiki/WebKitGTK/DependenciesPolicy. WebKitGTK 2.32 has already been branched so Ubuntu has until September, when WebKitGTK 2.34 will be released, to figure out what to do. You should still be able to build for Ubuntu 18.04 if you build your own CMake.

[Yury Semikhatsky]

Hi Michael, thanks for quick response and for the pointer to the policy! I ended up building cmake from source for now, should fix the problem.

[Michael Catanzaro]

Note that the patch in bug #181916 depends on cmake 3.12.
