No build type is debug but previously when I didn't pass
-DCMAKE_OSX_DEPLOYMENT_TARGET=10.10 -DCMAKE_OSX_SYSROOT=`xcrun options ,
with Debug build type size is very less. 7 GB is very unusual.
http://llvm.org/docs/GettingStarted.html according to this guide even with
Debug build type total size could go about 3 GB .
