Question

CMakeLists：

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

CMake 2.8.12 + MSVC 2015

配置输出：

提到https://cmake.org/pipermail/cmake/2009-March/027990.html。

您很可能没有设置类和/或函数调用出口。如果没有导出的类/函数，Visual Studio将不会为您生成一个导入库。

但添加CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS ON会得到相同的结果。

如何使MSVC生成lib＆amp; dll喜欢mingw？

更新cmake 2.8到3.4解决了问题。

MSVC不会通过cmake生成lib
