Couchbase-lite-C failed to build w/ CMake on MacOSX

Mobile Couchbase Lite
1

Hello,

I am unable to build with CMake 3.14.5 on MacOSX. I followed the instructions and ran build.sh.

I have encountered 2 problems. I was able to solve the first but have found no solution for the second.

The first problem was a large sequence of errors starting with

In file included from /Users/zbh8jv/Desktop/couchbase-lite-C/src/CBLDatabase.cc:19:
In file included from /Users/zbh8jv/Desktop/couchbase-lite-C/src/CBLDatabase_Internal.hh:23:
In file included from /Users/zbh8jv/Desktop/couchbase-lite-C/src/Listener.hh:22:
/Users/zbh8jv/Desktop/couchbase-lite-C/vendor/couchbase-lite-core/LiteCore/Support/access_lock.hh:66:43: error: 
      no template named 'remove_reference_t' in namespace 'std'; did you
      mean 'remove_reference'?
        using LOCK = std::lock_guard<std::remove_reference_t<MUTEX>>;

which I was able to fix by setting CMAKE_CXX_STANDARD to 14.

The second problem generates the following error message

I am aware Xcode can be used (and I was able to), but for my purposes I need to build it through Cmake. Any help will be appreciated. Further info:

CMake version 3.14.5
Mac OSX Mojave 10.14.6
AppleClang 10.0.1.10010046

Thanks in advance

Oops, looks like I haven’t kept the CMake files up to date. I’ll fix them.
