Связывание статических библиотек c и повторная компиляция ошибки с -fPIC

Получение большого количества «неопределенных ссылок на» ошибки.Чего мне не хватает в моем CMakeLists.txt?Разве я не связываю библиотеку должным образом?

native-lib должен быть связан с библиотеками liblept.a и libtesseract.a, которые, я думаю, не связаны с этими библиотеками.

Вот мойCMakeLists.txt: 

cmake_minimum_required(VERSION 3.4.1)


set(distribution_DIR ${CMAKE_CURRENT_SOURCE_DIR}/../../../../distribution)

add_library(lib_musireader STATIC IMPORTED)
set_target_properties(lib_musireader PROPERTIES IMPORTED_LOCATION
        ${distribution_DIR}/musireader/lib/${ANDROID_ABI}/libMusiReader.a)

add_library(lib_lept STATIC IMPORTED)
set_target_properties(lib_lept PROPERTIES IMPORTED_LOCATION
        ${distribution_DIR}/leptonica/lib/${ANDROID_ABI}/liblept.a)

add_library(lib_tesseract STATIC IMPORTED)
set_target_properties(lib_tesseract PROPERTIES IMPORTED_LOCATION
        ${distribution_DIR}/tesseract/lib/${ANDROID_ABI}/libtesseract.a)
add_library( # Sets the name of the library.
        native-lib
        SHARED
        native_lib.c)

find_library( 
        log-lib
        log)

target_include_directories(native-lib PRIVATE
        ${distribution_DIR}/musireader/include
        ${distribution_DIR}/leptonica/include
        ${distribution_DIR}/tesseract/include)

target_link_libraries( # Specifies the target library.
        native-lib
        lib_musireader
        lib_lept
        lib_tesseract


        # Links the target library to the log library
        # included in the NDK.
        ${log-lib})

Вот ошибки сборки, которые я получаю:

Я исправил свои ошибки, просто перекомпилировав библиотеки с флагом -fPIC .

как в make-файле: 

CFLAGS += -fPIC
CPPFLAGS += -fPIC

вы ссылаетесь на lib_lept, но имя вашей библиотеки liblept, поэтому вам нужно изменить все вхождения с lib_lept на liblept или изменить имя библиотеки liblept.a на lib_lept.a в зависимости от того, чтоВы предпочитаете.

Это также относится к libtesseract и другим библиотекам.
