I still need help... questions -
How do I get the android build to stop using the C++ headers under "Release+Asserts/include" next to its own clang path? Those are absolutely conflicting with the ones in my ndk. If I move the dir out of the way, it builds the arm64 files fine, but the mac (host) builds fail to find c++ headers which brings me to.. I care zero about the host files, why is this thing building files for x64 mac when I'm trying to build for andriod?? Can I force the build system to skip building for mac and only build the android libs? All I need is a working libv8_monolithic.a. I care nothing about d8 or any unit tests or any of the other stuff.
