【问题描述】：

我有我在 Cmake 中创建的共享对象，但我需要将它链接到另一个 .so 文件。我怎么做？这是我的 CMakeList.txt 文件

cmake_minimum_required(VERSION 3.9)
project(DAL VERSION 1.0.1 DESCRIPTION "DAL - Data Access Layer this class connect with the sql data base throw the Connection class")
set(CMAKE_CXX_STANDARD 17)

include(GNUInstallDirs)
add_library(DAL SHARED
        src/AppSettingDAL.cpp
        src/AppSettingEntity.cpp
        src/SettingsModificationDAL.cpp
        src/SymbolDAL.cpp
        src/SymbolInfoEntity.cpp
        )

set_target_properties(DAL PROPERTIES
        VERSION ${PROJECT_VERSION}
        SOVERSION 1
        PUBLIC_HEADER
        include/AppSettingsDAL.hpp
        include/SettingsModificationDAL.hpp
        include/AppSettingEntity.hpp
        include/SymbolDAL.hpp
        include/SymbolInfoEntity.hpp
        )
configure_file(DAL.pc.in DAL.pc @ONLY)
target_include_directories(DAL PRIVATE .)
install(TARGETS DAL
        LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}
        PUBLIC_HEADER DESTINATION ${CMAKE_INSTALL_INCLUDEDIR})
install(FILES ${CMAKE_BINARY_DIR}/DAL.pc DESTINATION ${CMAKE_INSTALL_DATAROOTDIR}/pkgconfig)

我希望它链接到 lib connlib.so

标签： c++ cmake shared-libraries

【解决方案1】：

add_executable(DAL ...)
target_link_libraries(DAL connlib)

（注意：不要包含 EXT。它将由 cmake 基于您的操作系统完成。）
