# TODO(mmoss): Make only supports (theoretically) a single, global build
# directory (through GYP_GENERATOR_FLAGS 'output_dir'), rather than
# gyp-file-specific settings (e.g. the stuff in builddir.gypi) that the other
# generators support, so this doesn't work yet for make.
# TODO(mmoss) Make also has the issue that the top-level Makefile is written to
# the "--depth" location, which is one level above 'src', but then this test
# moves 'src' somewhere else, leaving the Makefile behind, so make can't find
# its sources. I'm not sure if make is wrong for writing outside the current
# directory, or if the test is wrong for assuming everything generated is under
# the current directory.
# Android does not support setting the build directory.
