Bug 218566 – JSC build fails on Big Sur 11.0.1 beta

• Component: CMake
• Status: RESOLVED FIXED

[Sergey Rubanov]

On macOS 11 Big Sur /usr/lib/*.dylib files do not exist. That causes "Tools/Scripts/build-jsc --jsc-only" to fail (it needs /usr/lib/libicucore.dylib).

> New in macOS Big Sur 11.0.1 beta, the system ships with a built-in dynamic linker cache of all system-provided libraries. As part of this change, copies of dynamic libraries are no longer present on the filesystem. Code that attempts to check for dynamic library presence by looking for a file at a path or enumerating a directory will fail. Instead, check for library presence by attempting to dlopen() the path, which will correctly check for the library in the cache. (62986286)

r- for the cmake minimum version change.

Is this needed to use the find_library() function?

I only have 3.17.x installed on my macOS 10.15.6 system, so I think this would break (Apple) folks using CMake on macOS.

[Sergey Rubanov]

Oh, actually cmake minimum required version update is not required, I misunderstood this issue at first https://gitlab.kitware.com/cmake/cmake/-/issues/21007 and forgot to remove this change in CMakeLists

Nit: Add period at the end of the comment.  (Not necessary to land, but you might want to make this change while fixing the ChangeLog.)

Nit: Remove this line as this file is no longer changed.

Can you set cq+, or do I need to do it?  (I didn't want to set it if you had planned to later.)

Sorry, I'm new here and this is my first patch =)
What is cq+ or where can I read about that?
