CMakeLists:

if (MSVC)
    set(CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS ON)
endif()
add_library(${PROJECT_NAME} SHARED ${SOURCES})

CMAKE 2.8.12+MSVC 2015年

配置输出:

您很可能没有将类和/或函数调用设置为出口。如果没有导出的类/函数,visual studio将不会为您生成导入库。

但加入 CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS ON 得到同样的结果。

如何使msvc像mingw一样生成lib&dll?

更新 cmake 2.8到3.4解决了问题。
