LZ4 complication fails in v6-11-02 for macOS 10.13

ROOT
1

I downloaded the new version of root: v6-11-02 on macOS 10.13 (XCode 9). When compiling from source with the following options:
cmake …/root-git/ -Dgnuinstall=ON -Dbuiltin_gsl=ON -Dmathmore=ON -Dminuit2=ON -Droofit=ON

I get the following error:

[ 34%] Performing configure step for 'LZ4’
CMake Error at /Users/nmccoll/Dropbox/Work/programs/root/LZ4-prefix/src/LZ4-stamp/LZ4-configure-RelWithDebInfo.cmake:16 (message):

Hi,

thanks for the feedback.
We are working on those but there are a few residual issues with XCode9 as you noticed.

Cheers,

Hi Nick,

I answered perhaps too quickly. I see you are interested in 10.13.
High Sierra will be supported for sure for the 6.12 release, foreseen for November: it’s just not yet ready.
This issue will be discussed in the team at the beginning of next week.

Thanks Danilo!

I understand that support for new OS’s take time, I just wanted to make sure that these problems were reported to facilitate that process.
