add cmake generate method

[holylong]

增加了连个CMakeLists.txt文件，增加了一种编译方式

mkdir build
cd build
cmake ..
cmake --build .
cd Debug
TrafficMonitor.exe

有个问题，如果我在工程中添加或删除的cpp或h文件，那么CMakeList.txt文件也要相应更新，cmake好像还支持*.cpp这种通配符的写法吧。

[holylong]

支持，我直接从vcxproj里边复制进来的内容没有做*.cpp的修改

建议使用aux_source_directory这样的语句来添加代码文件到CMake工程

改了一版

分支拉下来跑了一下，使用CMake 3.24.0-rc2，Ninja 1.11.0构建出错。

但是使用Visual Studio 2022作generator是没问题的，但是有CMake警告。

[cmake] CMake Warning in OpenHardwareMonitorApi/CMakeLists.txt:
[cmake] For the target "OpenHardwareMonitorApi" the /clr compiler flag was added
[cmake] manually. Set usage of C++/CLI by setting COMMON_LANGUAGE_RUNTIME target
[cmake] property.
[cmake]
[cmake]

顺便建议给MSVC补上 /MP 加速编译。

edit 考虑把 build 和 out 文件夹放进 .gitignore 文件里面

看了下，想要Ninja这类非Visual Studio生成器支持clr比较困难，需要手动补充/FU选项或者在代码中使用#using语句，所以这块先不管了（摆烂）。

添加/MP后，CMake直接build还是没有使用多核编译，但是使用VS打开项目再编译是有效的，所以我写了个target。

if(CMAKE_GENERATOR MATCHES "Visual Studio")
    add_custom_target(BUILD_ALL_WITH_MP_OPTION
        COMMAND ${CMAKE_COMMAND} --build ${CMAKE_BINARY_DIR} --target ALL_BUILD --config $<CONFIGURATION> -- -m)
endif()

即直接给调用MSBuild的命令后面补了个 -m 选项。使用CMake编译时选BUILD_ALL_WITH_MP_OPTION目标，就可以启用多核编译了。
