CMake：在make build期间找不到库

Question

我正在尝试设置一个工作区，在那里我可以尝试GLib教程。我不熟悉C编程以及进行构建。

运行make命令时出现以下错误。

/Applications/CMake.app/Contents/bin/cmake -S/Users/foo/workspaces/personal/c/glib_tut/hello_world -B/Users/foo/workspaces/personal/c/glib_tut/hello_world --check-build-system CMakeFiles/Makefile.cmake 0

make[2]: *** [hello] Error 1
make[1]: *** [CMakeFiles/hello.dir/all] Error 2
make: *** [all] Error 2

以下是我的CmakeLists.txt

cmake_minimum_required(VERSION 3.10)

project (hello_world_project)
include_directories(include)

find_package(PkgConfig REQUIRED)
pkg_check_modules(GLIB REQUIRED glib-2.0)

message(INFO "libs:" ${GLIB_LIBRARIES})
message(INFO "includes:" ${GLIB_INCLUDE_DIRS})

file(GLOB SOURCES "src/*.c")

#Create an executable
add_executable(hello ${SOURCES})

target_include_directories(hello PUBLIC 
    ${GLIB_INCLUDE_DIRS}
)

target_link_libraries(hello PUBLIC 
    ${GLIB_LIBRARIES}
)

我的cmake命令成功完成，并显示以下日志：

有人可以指导我解决此问题吗？在此先感谢

Static Library出现的Static Linker是编译时错误

ld: library not found for -l<Library_name>

没有包含Library not found for的库路径，则会出现错误Library Search Paths。>

ld表示Static Linker，它找不到库的位置。作为开发人员，您应该帮助链接程序并指向Library Search Paths

Build Settings -> Search Paths -> Library Search Paths
