Windows上的Cmake和dll/lib链接

Question

我正在使用mingw和cmake在窗户上工作。

有人提供一个带有lib，dll和标头文件的库。我可以在Visual Studio项目中很容易使用它。但是我无法将其集成到CMAKE项目中。关于此主题已经有很多问题，但仅用于Linux，或使用CMAKE构建图书馆或可用来源的图书馆，或者与我相同的用例，但是在评论中有很多勘误表明答案是答案是永远不要完全正确...

我想在我的 foo 库中使用 foo_function 在我的 bar 项目中。我没有这个 foo 项目的来源。只有DLL，LIB和标题文件。

BarProject
           ├───       
           ├─── CMakeLists.txt  
           ├─── Foo
                          ├─── include       
                                  └─── foo.h
                          ├─── x64        
                                 |─── foo.dll
                                 └─── foo.lib
           └─── main_bar.c

这是我的 cmakelists.txt文件的内容：

cmake_minimum_required(VERSION 3.10)
# set the project name and version
project(bar VERSION 1.0)

# add the executable
add_executable(bar main_bar.c)

target_include_directories(bar PUBLIC "${PROJECT_BINARY_DIR}" "foo/include")

add_library(foo SHARED IMPORTED)
set_property(TARGET foo PROPERTY
             IMPORTED_LOCATION "${CMAKE_SOURCE_DIR}/Foo/x64/foo.dll")
set_property(TARGET foo PROPERTY
             IMPORTED_IMPLIB "${CMAKE_SOURCE_DIR}/Foo/x64/foo.lib")
target_link_libraries(bar PRIVATE foo)

set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_SUPPRESS_REGENERATION true)

set_property(DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY VS_STARTUP_PROJECT bar)

Finally to test my work :

        $ ls
        main_bar.c CMakeLists.txt Foo
        $ mkdir tutu
        $ cd tutu
        $ cmake .. && cmake  --build . -v

汇编步骤运行良好，问题在链接步骤中。

编辑：

确定在Ben Voigt的评论后，我选择探索使用Mingw中使用GCC/G ++编译器的解决方案，而不是使用CL/Visual Studio Thing。

新的测试过程：

$ cmake .. -G "MinGW Makefiles" && cmake --build . -v
(...)

好的结果是相同的，但至少，命令行和工具对我来说更熟悉。 我在命令行中找不到对FOO库的任何引用。然后我检查文件linklibs.rsp，我们在这里：

$ cat CMakeFiles/bar.dir/linklibs.rsp
 -lm *Foo/x64/foo.lib* -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32

这是预期的结果吗？
