#
# With NDK r16, 'Unified Headers' is the only way to build against the NDK and
# the API-level specific headers are not shipped anymore. A migration guide is
# available from https://android.googlesource.com/platform/ndk/+/ndk-release-r16/docs/UnifiedHeaders.md
# and we follow that when setting up these paths. One thing to note however
# is that the 'Unified Headers' ship headers that contain API-level guarded
# functions so we may need to replace or override headers. One such example
# is iconv.h which at the time of writing, has a header in the NDK
# with no usable functions. This simply means that we have to construct
# cflags/cppflags/ldflags/etc to look in our directories before looking into
# the sysroot.

# toolchain_path: location of the compiler binaries
# sysroot: location of the API-level libraries (no headers)
