error: missing opencv_features2d (STATIC_LIBRARIES android-arm)" - opencv

Question

I've created an application to read QR code using OpenCv.
When I try to build it using NDK, everything works well
NDK=/opt/android-ndk-r23c
export TOOLCHAIN=$NDK/toolchains/llvm/prebuilt/linux-x86_64
export TARGET=aarch64-linux-android
export API=21
export AR=$TOOLCHAIN/bin/llvm-ar
export CC=$TOOLCHAIN/bin/$TARGET$API-clang
export AS=$CC
export CXX=$TOOLCHAIN/bin/$TARGET$API-clang++
export LD=$TOOLCHAIN/bin/ld
export RANLIB=$TOOLCHAIN/bin/llvm-ranlib
export STRIP=$TOOLCHAIN/bin/llvm-strip
$NDK/ndk-build
But when I've tried to build it as a system application as part of the AOSP build I've got an error:
read_qr/jni/../../OpenCV-android-sdk/sdk/native/jni/OpenCV.mk: error: "read_qr (EXECUTABLES android-arm) missing opencv_features2d (STATIC_LIBRARIES android-arm)"
You can set ALLOW_MISSING_DEPENDENCIES=true in your environment if this is intentional, but that may defer real problems until later in the build.
read_qr/jni/../../OpenCV-android-sdk/sdk/native/jni/OpenCV.mk: error: "read_qr (EXECUTABLES android-arm) missing opencv_dnn (STATIC_LIBRARIES android-arm)"
You can set ALLOW_MISSING_DEPENDENCIES=true in your environment if this is intentional, but that may defer real problems until later in the build.
build/make/core/main.mk:1118: error: exiting from previous errors.
22:44:58 ckati failed with: exit status 1
And I have no idea what can be the problem.
This is my Android.mk and Application.mk files:
Android.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
# Location of SDK on my drive
OPENCVROOT := ${LOCAL_PATH}/../../OpenCV-android-sdk
OPENCV_CAMERA_MODULES := off
OPENCV_INSTALL_MODULES := on
OPENCV_LIB_TYPE := STATIC
TARGET_ARCH_ABI := armeabi-v7a
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
# Load your local .cpp and .h files here.
LOCAL_SRC_FILES := readQr.cpp
LOCAL_LDLIBS := -lm -llog -ldl -lz
LOCAL_CPPFLAGS += -fexceptions -frtti -std=c++17
LOCAL_LDFLAGS += -ljnigraphics
LOCAL_C_INCLUDES += ${OPENCVROOT}/sdk/native/jni/include \
${OPENCVROOT}/sdk/native/jni/include/opencv2
LOCAL_EXPORT_C_INCLUDES += ${OPENCVROOT}/sdk/native/jni/include \
${OPENCVROOT}/sdk/native/jni/include/opencv2
LOCAL_MODULE := read_qr
include $(BUILD_EXECUTABLE)
APP_PLATFORM := android-21
Application.mk
APP_STL := c++_static
APP_CPPFLAGS += -fexceptions -frtti -std=c++11 -D__STDC_CONSTANT_MACROS
APP_ABI := armeabi-v7a
APP_PLATFORM := android-21
Can someone help me to understand what is the problem?

Resolved by changing the Android.mk
from:
include $(BUILD_EXECUTABLE)
to
include $(BUILD_STATIC_EXECUTABLE)
