The build failed on my Mac:

[  7%] Performing install step for 'leveldb'
cp: the -R and -r options may not be specified together.
make[2]: *** [libs/3rdparty/leveldb-prefix/src/leveldb-stamp/leveldb-install] Error 1
make[1]: *** [libs/3rdparty/CMakeFiles/leveldb.dir/all] Error 2
make: *** [all] Error 2

I looked it up online: On Linux, -R and -r do the same thing. On Mac, -R is the equivalent of them and -r is an obsolete parameter:

COMPATIBILITY
     Historic versions of the cp utility had a -r option.  This implementation supports that option; however,
     its use is strongly discouraged, as it does not correctly copy special files, symbolic links, or fifo's.

Here's another error:

Update: I found that its equivalent on Mac is SO_NOSIGPIPE and added the fix
