linux CMake链接静态库和Glib错误

我对Cmake的工作原理有一个相当初级的了解。我有一个项目，其中包括一个静态库，而静态库反过来又依赖于glib。我遗漏了一些导致大量undefined references to glib features的东西，就像下面这些一样。我在Linux Ubuntu中工作，并且有Cmake 3.5

../Gobbledegook/src/libggk.a(libggk_a-Gobbledegook.o): In function `ggkWait':
/home/ubuntu/visionpro-device-xray/src/user_device_interface/Gobbledegook/src/Gobbledegook.cpp:384: undefined reference to `g_set_print_handler'
/home/ubuntu/visionpro-device-xray/src/user_device_interface/Gobbledegook/src/Gobbledegook.cpp:385: undefined reference to `g_set_printerr_handler'
/home/ubuntu/visionpro-device-xray/src/user_device_interface/Gobbledegook/src/Gobbledegook.cpp:386: undefined reference to `g_log_set_default_handler'

这是我的Cmake文件，我尝试自己构建库-不链接静态库。我尝试使用/包含的库是https://github.com/nettlep/gobbledegook。

cmake_minimum_required(VERSION 3.2.2)
project(TestBLE)

set(CMAKE_BUILD_TYPE Debug)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -I/usr/include/glib-2.0")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/usr/lib/aarch64-linux-gnu/glib-2.0/include")

find_package(PkgConfig REQUIRED)
pkg_search_module(GLIB REQUIRED glib-2.0)
include_directories(${GLIB_INCLUDE_DIRS})
link_directories(${GLIB_LIBRARY_DIRS})

set(THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)

# Gets all the header/source files in current directory
file(GLOB SOURCES "*.cpp")
file(GLOB HEADERS "*.h")

file(GLOB GGK_SOURCES "Gobbledegook/src/*.cpp")
file(GLOB GGK_HEADERS "Gobbledegook/src/*.h")

add_executable(
        ${PROJECT_NAME}
        ${SOURCES}
        ${HEADERS}
        ${CMAKE_SOURCE_DIR}/Gobbledegook/include/Gobbledegook.h
        ${GGK_SOURCES}
        ${GGK_HEADERS}
)

target_link_libraries( 
        ${PROJECT_NAME}
        ${GLIB_LIBRARIES}
        Threads::Threads
)

下面是我的CMake文件，它试图链接静态库libggk.a，该静态库是用Gobbledegook库中的./configure && make构建的。

cmake_minimum_required(VERSION 3.2.2)
project(TestBLE)

set(CMAKE_BUILD_TYPE Debug)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -I/usr/include/glib-2.0")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/usr/lib/aarch64-linux-gnu/glib-2.0/include")

find_package(PkgConfig REQUIRED)
pkg_search_module(GLIB REQUIRED glib-2.0)
include_directories(${GLIB_INCLUDE_DIRS})
link_directories(${GLIB_LIBRARY_DIRS})

set(THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)

# Gets all the header/source files in current directory
file(GLOB SOURCES "*.cpp")
file(GLOB HEADERS "*.h")

add_executable(
        ${PROJECT_NAME}
        ${SOURCES}
        ${HEADERS}
        ${CMAKE_SOURCE_DIR}/Gobbledegook/include/Gobbledegook.h
)

target_link_libraries( 
        ${PROJECT_NAME}
        ${GLIB_LIBRARIES}
        Threads::Threads
        ${CMAKE_SOURCE_DIR}/Gobbledegook/src/libggk.a
)

在这两种情况下我都保留了未定义的引用。感谢大家的帮助，我一直在论坛上寻找提示或解释。

我发现了这个问题，它与需要包含gtk+-2.0有关。我不知道为什么gtk+-2.0在我链接的库中使用，因为它不是一个图形程序。CmakeLists.txt应该如下所示。

cmake_minimum_required(VERSION 3.2.2)
project(TestBLE)

set(CMAKE_BUILD_TYPE Debug)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall")   #All warning
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wextra") #Extra warning flags

find_package(PkgConfig REQUIRED)

pkg_check_modules(GLIB REQUIRED glib-2.0)
include_directories(${GLIB_INCLUDE_DIRS})

pkg_check_modules(GTK2 REQUIRED gtk+-2.0)

set(THREADS_PREFER_PTHREAD_FLAG ON)
FIND_PACKAGE(Threads REQUIRED)

file(GLOB GGK_SOURCES "Gobbledegook/src/*.cpp")
file(GLOB GGK_HEADERS "Gobbledegook/src/*.h")

add_executable(
        ${PROJECT_NAME}
        ${SOURCES}
        ${HEADERS}
        #${CMAKE_SOURCE_DIR}/Gobbledegook/include/Gobbledegook.h
        ${GGK_SOURCES}
        ${GGK_HEADERS}
)

target_include_directories(
    ${PROJECT_NAME}
    PUBLIC ${GLIB_INCLUDE_DIRS}
)

target_link_libraries( 
        ${PROJECT_NAME}
        PUBLIC ${GLIB_LIBRARIES}
        PUBLIC ${GTK2_LIBRARIES}
        Threads::Threads
)

希望这能帮助其他试图将gobbledegook库合并到他们的构建中的人。
