Module 目标链接库在链接时错误地拉入模块库 我使用CMAD3.2.2..< /P>有两个C++项目

第一个是模块库（一个动态加载的插件）。它为CMake安装DLL、头文件和配置文件

cmake_minimum_required(VERSION 3.12 FATAL_ERROR)
project(MyPlugin LANGUAGES CXX)
set(CMAKE_DEBUG_POSTFIX "d")

# MODULE libraries are dynamically loaded at runtime and never linked against
add_library(MyPlugin MODULE
    include/a.h
    src/a.cpp
    src/b.h
    src/b.cpp
)

target_include_directories(MyPlugin
    PUBLIC
        $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/include>
        $<INSTALL_INTERFACE:include/MyPlugin>
    PRIVATE
        src
)

install(TARGETS MyPlugin EXPORT MyPluginConfig
    # MODULE libraries are installed as LIBRARY
    LIBRARY DESTINATION plugins COMPONENT Runtime
    RUNTIME DESTINATION bin COMPONENT Runtime
    PUBLIC_HEADER DESTINATION include/MyPlugin COMPONENT Development
)
install(FILES $<TARGET_PDB_FILE:MyPlugin> DESTINATION plugins OPTIONAL COMPONENT Runtime)
install(
    DIRECTORY include/
    DESTINATION include/MyPlugin
    FILES_MATCHING PATTERN "*.h"
)
install(EXPORT MyPluginConfig
    NAMESPACE MyPlugin::
    DESTINATION lib/cmake/MyPlugin
)

使用vs2015生成的解决方案，链接失败，因为插件DLL是在链接可执行文件的过程中提供的

有没有人可以解决这个问题，或者我应该提交一个bug

关于。

此问题的解决方案是将库一分为二：只提供头的接口库和不导出任何头的模块库

模块库

CMakeLists.txt

变为：
