# Generates rules to install sanitizer runtime libraries to the out directory if
# the sanitizer is requested in the app's ldflags.
#
# Args:
#   NDK_SANTIZER_NAME:
#       Sanitizer name used as the variable name component to find the library.
#       i.e. $(TARGET_$(2)_BASENAME) is the name of the library to install. This
#       is also used as the name printed to the terminal for the build step.
#   NDK_SANITIZER_FSANITIZE_ARGS:
#       -fsanitize= arguments that require this runtime library.
#
# Example usage:
#   NDK_SANITIZER_NAME := UBSAN
#   NDK_SANITIZER_FSANITIZE_ARGS := undefined
#   include $(BUILD_SYSTEM)/install_sanitizer.mk
