Question

这是项目树：它是一个使用另一个静态库的静态库

Static_lib/
    |
    ----src/
        |----src1.cpp
        |----src2.cpp
    ----inc/
        |----head1.h
        |----head2.h
    ----Static_lib2/
        |----lib/
            |----32/
                |Debug/
                    lib2.lib
                |Release/
                    lib2.lib
            |----64/
                |Debug/
                    lib2.lib
                |Release/
                    lib2.lib
        |----include/
            |bunch of headers
    ----build/
    ----CMakeLists.txt

这是我的CMakeLists.txt：

cmake_minimum_required(VERSION 3.5.1)
project(Static_lib)

set(SOURCE_FILES src/src1.cpp src/src2.cpp)
set(HEADER_FILES inc/head1.h inc/head2.h)

add_library(Static_lib STATIC ${SOURCE_FILES} ${HEADER_FILES})

target_include_directories(Static_lib PUBLIC 
    ${CMAKE_SOURCE_DIR}/inc 
    ${CMAKE_SOURCE_DIR}/Static_lib2/include
)

if(CMAKE_SYSTEM_NAME STREQUAL Linux)

    if(CMAKE_SIZEOF_VOID_P EQUAL 8)
        set_property(GLOBAL PROPERTY FIND_LIBRARY_USE_LIB32_PATHS FALSE)
    else(CMAKE_SIZEOF_VOID_P EQUAL 8)
        set_property(GLOBAL PROPERTY FIND_LIBRARY_USE_LIB32_PATHS TRUE)
    endif(CMAKE_SIZEOF_VOID_P EQUAL 8)

    find_library(STATIC_LIB2 libcrypto.a)
    target_link_libraries(Static_lib "${STATIC_LIB2}")

elseif(CMAKE_SYSTEM_NAME STREQUAL Windows)

    if(CMAKE_SIZEOF_VOID_P EQUAL 8)
        target_link_libraries(Static_lib debug ${CMAKE_SOURCE_DIR}/Static_lib2/lib/64/Debug/lib2.lib)

        target_link_libraries(Static_lib optimized ${CMAKE_SOURCE_DIR}/Static_lib2/lib/64/Release/lib2.lib)

    else(CMAKE_SIZEOF_VOID_P EQUAL 8)
        target_link_libraries(Static_lib debug ${CMAKE_SOURCE_DIR}/Static_lib2/lib/32/Debug/lib2.lib)

        target_link_libraries(Static_lib optimized ${CMAKE_SOURCE_DIR}/Static_lib2/lib/32/Release/lib2.lib)

    endif(CMAKE_SIZEOF_VOID_P EQUAL 8)

endif(CMAKE_SYSTEM_NAME STREQUAL Linux)

当我使用Visual Studio生成器创建项目时，创建的项目没有错误或警告，但是项目属性中没有依赖项和库。

在构建之后，我得到的库实际上没有它应该具有的大小。

有人可以提供一些见解吗？也许我的CMakeLists代码错了？

提前致谢！

我刚刚在cmake: include library dependencies in static lib

找到答案

默认情况下，静态库不会合并在一起。手动完成是可行的方法。

CMake - 未在MSVC下显示的链接库
