android ndk - New to makefile -- looks like target depends on non-existent prerequisite -


i'm studying makefile , i'm trying understand what's happening.

gypandroid.mk: ./deps/gyp example/libtextsort.gyp support-lib/support_lib.gyp example/example.djinni  ./example/run_djinni.sh  android_build_top=$(android_ndk_home) deps/gyp/gyp --depth=. -f android -dos=android -icommon.gypi example/libtextsort.gyp --root-target=libtextsort_jni

with understanding of make, says "gypandroid.mk target depends on 4 other targets:"

1) ./deps/gyp

2) example/libtextsort.gyp

3) support-lib/support_lib.gyp

4) example/example.djinni

however, search through entire project targets #2 , doesn't exist anywhere else. there use of prerequisite i'm missing? what's happening here?

full makefile reference:
