при компиляции freetype для android, не найден ft2build.h

Хочу скомпилировать игру для android на sdl2. Скачал с github freetype для android. Я создал в jni каталог Freetype2 и в него закинул include src и Android.mk. Вот Android.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
FREETYPE_SRC_PATH := 
LOCAL_MODULE := freetype2-static
LOCAL_CFLAGS := -DANDROID_NDK \
                -DFT2_BUILD_LIBRARY=1
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include_all \
                $(FREETYPE_SRC_PATH)include \
                $(FREETYPE_SRC_PATH)src
LOCAL_SRC_FILES := \
        $(FREETYPE_SRC_PATH)src/autofit/autofit.c \
        $(FREETYPE_SRC_PATH)src/base/basepic.c \
        $(FREETYPE_SRC_PATH)src/base/ftapi.c \
        $(FREETYPE_SRC_PATH)src/base/ftbase.c \
        $(FREETYPE_SRC_PATH)src/base/ftbbox.c \
        $(FREETYPE_SRC_PATH)src/base/ftbitmap.c \
        $(FREETYPE_SRC_PATH)src/base/ftdbgmem.c \
        $(FREETYPE_SRC_PATH)src/base/ftdebug.c \
        $(FREETYPE_SRC_PATH)src/base/ftglyph.c \
        $(FREETYPE_SRC_PATH)src/base/ftinit.c \
        $(FREETYPE_SRC_PATH)src/base/ftpic.c \

LOCAL_LDLIBS := -ldl -llog
include $(BUILD_STATIC_LIBRARY)

пишет такую ошибку, когда я запускаю ./gradlew installDebug

но этот файл есть в include/. Я пробывал поменять его на "ft2build.h", но тоже самое, не видит этого файла.
