xproj fails to build — GLFW/glfw3.h not found

[1ec5]

1. Clean and distclean everything.
2. make xproj
3. Build the osxapp target.

In file included from /Users/mxn/hub/mapbox-gl-native/macosx/main.mm:6:
../include/mbgl/platform/default/glfw_view.hpp:9:10: fatal error: 'GLFW/glfw3.h' file not found
#include <GLFW/glfw3.h>

I also see lots of warnings in mbgl-render of the form:

ld: warning: direct access in void boost::throw_exception<boost::bad_lexical_cast>(boost::bad_lexical_cast const&) to global weak symbol typeinfo for boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_lexical_cast> > means the weak symbol cannot be overridden at runtime. This was likely caused by different translation units being compiled with different visibility settings.

Xcode 6.4 on OS X 10.10.4. Possibly related to #2016.

Possibly a regression from #1988.

Doing a make distclean, then make xproj here builds fine for me in Xcode 6.4.

Also no sign of the boost logs either with running the gamut of interactive tests on OS X.

After distclean, I encounter the GLFW errors in master but not release-0.5.0. I’m bisecting right now, but it’ll take awhile.

I must’ve had some cruft lying around. After a bunch of bisecting, I no longer get the GLFW compiler error, although the Boost linker warnings remain.
