# When building this project, we actually generate several components which
# are the following:
#
#  - the emulator-ui program (which is target-agnostic)
#  - the target-specific qemu-android-$ARCH programs (headless emulation engines)
#  - the "standalone" emulator programs (embed both UI and engine in a single
#    binary and process), i.e. "emulator" for ARM and "emulator-x86" for x86.
#
# This file defines static host libraries that will be used by at least two
# of these components.
