CMake-设置将库添加到共享会导致致命错误U1073:don'；我不知道怎么做

这是我的根项目

CMakeLists.txt

这是我的

库CMakeLists.txt：

    # Link the MySQL library to your executable.
    target_link_libraries(Common PUBLIC

    target_include_directories(Common PUBLIC ${CMAKE_CURRENT_SOURCE_DIR})

当我将
Common-SHARED
更改为
Common-STATIC
时，一切正常。但是，为什么我无法将其设置为
SHARED
接收以下错误：

[ 46%] Built target Common
NMAKE : fatal error U1073: don't know how to make 'bin\lib\Common.lib'
Stop.
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.24.28314\bin\HostX64\x64\nmake.exe"' : return code '0x2'
Stop.

你能告诉我为什么我会收到这个错误吗？
闻起来好像你忘了从
公共库导出符号。如果不导出符号，则不会创建导入文件（
.lib
）。请您回答我该怎么做，好吗？只需通过谷歌搜索dllexport/dllimport，网络上有很多示例。
