add_library 无法在 CMake 中添加 CSharp 源文件？

我正在尝试从一组构建 CSharp DLL.cs文件。我用的是add_library()函数添加源文件（.cs文件）。但它给出了诸如“add_library for library libname without any source files”之类的警告。请提供一个解决方案以使其正常工作。

提前致谢。

CMakeLists.txt 是：

cmake_minimum_required(VERSION 2.8)

project(MyAddIn)

AUX_SOURCE_DIRECTORY(${CMAKE_CURRENT_SOURCE_DIR}/MyAdd-In/ MyAddIn_SOURCES)     


SET_SOURCE_FILES_PROPERTIES(${MyAddIn_SOURCES} PROPERTIES LANGUAGE CSharp)

ADD_LIBRARY(AddInTrg SHARED ${MyAddIn_SOURCES})

SET_TARGET_PROPERTIES(AddInTrg PROPERTIES 
                               LINKER_LANGUAGE CSharp
                               RUNTIME_OUTPUT_DIRECTORY bin
                               RUNTIME_OUTPUT_DIRECTORY_DEBUG bin
                               RUNTIME_OUTPUT_NAME MyAddIn_Bin
                               ARCHIVE_OUTPUT_DIRECTORY lib
                               ARCHIVE_OUTPUT_DIRECTORY_DEBUG lib
                               OUTPUT_NAME MyAddIn_Bin)

add_custom_command(OUTPUT ${CMAKE_BINARY_DIR}/bin/MyAddIn_Bin.dll
                   WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}/MyAdd-In
                   COMMAND C:/WINDOWS/Microsoft.NET/Framework/v3.5/csc.exe
                   ARGS 
                   -target:library                 
                   -out ${CMAKE_CURRENT_BINARY_DIR}/bin/MyAddIn_Bin.dll
                   "${CMAKE_CURRENT_SOURCE_DIR}/MyAdd-In/Ribbon.cs" "${CMAKE_CURRENT_SOURCE_DIR}/MyAdd-In/ThisAddIn.cs" "${CMAKE_CURRENT_SOURCE_DIR}/MyAdd-In/Ribbon.xml"
                   COMMENT "-- Generating AddIn Dll")

As of CMake 3.8，CMake 现在完全支持 C# 作为语言。您现在应该能够使用如下所示的内容创建 C# 程序集目标 (DLL)：

# Define the DLL target, including all relevant project files.
add_library(AddInTrg SHARED ${MyAddIn_SOURCES})

# Set the .NET Framework version for the target.
set_property(TARGET AddInTrg PROPERTY VS_DOTNET_TARGET_FRAMEWORK_VERSION "v4.6.1")
# Set the C# language version (defaults to 3.0 if not set).
set(CMAKE_CSharp_FLAGS "/langversion:6")
# Add in some .NET reference libraries.
set_property(TARGET AddInTrg PROPERTY VS_DOTNET_REFERENCES
    "Microsoft.CSharp"
    "System"
    "System.Core"
    "System.Data"
    "System.Deployment"
    "System.Drawing"
    "System.Net.Http"
    "System.Xml"
)

您还可以使用 CMake 指定 .NET 和 C# 版本，并提取任何必需的 .NET 引用。

注意：此支持仅涵盖 Visual Studio 2010 及更高版本。
