You need to use the CMake option `CMAKE_OSX_SYSROOT` to manage the system root
because `lib/CMakeLists.txt` uses "CMAKE_OSX_SYSROOT" to find the correct
libc++abi.dylib.
Have you tried that? It is unfortunate that Linux and OS X use different
options for the same thing t

That works as well. I am not sure if there is any specific reason for using
"--sysroot" so I proposed a safer fix.

Why would we not use "-isysroot" on other platforms as well?

Sorry, made a typo on the previous patch.
A little background information. When the greendragon jenkins make an
system upgrade in the future, it will need this flag as well to build and
test libcxx through cmake/ninja.

@danalbert actually uses this option. I would like him to confirm this change.
