OK, then, I think we should remove Fuchsia related things in webkitdir.pm. We can pass cmakeargs by using `--cmakeargs`.
So basically, `Tools/Scripts/build-jsc --jsc-only --cmakeargs="-DCMAKE_TOOLCHAIN_FILE=XXX"` should work.

If we use JSCOnly port in Fuchsia OS, I think we do not need to check Fuchsia related things in webkitdirs.pm. We can just use `--jsc-only`, and we can remove Fuchsia related things in webkitdirs.pm.

Why not passing it with `cmakeargs`? `Tools/Scripts/build-jsc --cmakeargs="-DCMAKE_TOOLCHAIN_FILE=XXX"`

Minor: ‘ (single quote) => “ (double quote)

Although unwritten, we prefer double-quoted string literals over single quoted ones unless we explicitly do not want string interpolation or using single quotes reduces the need to escape characters in the string.

This will not work correctly if the path has spaces in its name. We should take a similar approach as done for -DCMAKE_INSTALL_PREFIX and surround $toolchainFile in quotes. Is there a better way to write this code to handle a path that has embedded space characters?

Neat!

Yes, that seems to work.  Done.

Good idea.

Removed.

Got it.  I've removed this code, in any case.

Apparently the best way to write this code is to delete it.  :)

Please update this ChangeLog as this function listing is out of date. It would be good to explain that we are removing code from webkitdir.pm (and why) as well as explain how to build by passing --cmakeargs “...” to build-webkit.

Done.

I've been putting that information on the wiki:
