在Cmake C＃项目中使用DLL

Question

I'm trying to use CMake to build a C# DLL. For this, I need to add a third party .dll to the project, so I can use some functions of it that I need.

The problem is, I can access the library, not even

using Namespace;

works, as the Namespace is not recognized.

# cmake version
cmake_minimum_required (VERSION 3.8)

# project
project ("VILAPI" CSharp)

# include directories
set(CMAKE_INCLUDE_CURRENT_DIR ON)

# source and library output paths and directories
set(SRCS_VILAPI "./src/main.cs")
set(OUT_DIR ${CMAKE_HOME_DIRECTORY}/bin)

# actual building process
add_library (${project} SHARED ${SRCS_VILAPI})

set_property(TARGET ${project} PROPERTY DOTNET_TARGET_FRAMEWORK_VERSION "v4.0")
set_property(TARGET ${project} PROPERTY WIN32_EXECUTABLE FALSE)
set_property(TARGET ${project} PROPERTY VS_CONFIGURATION_TYPE ClassLibrary)
set_property(TARGET ${project} PROPERTY VS_DOTNET_REFERENCES
    "System"
    "./lib/Vector.CANoe.TFS.dll"
)

set_target_properties(${project} PROPERTIES ARCHIVE_OUTPUT_DIRECTORY ${OUT_DIR})
set_target_properties(${project} PROPERTIES LIBRARY_OUTPUT_DIRECTORY ${OUT_DIR})

CMake doesn't throw an error. I've also tried to add it the following way:

set_property(TARGET ${project} PROPERTY     VS_DOTNET_REFERENCE_Vector.CANoe.TFS.dll "./lib/Vector.CANoe.TFS.dll")

which was suggested in an answer on stackoverflow, but it still does not work.

Answer 1

For third-party DLL references, you should be using VS_DOTNET_REFERENCE_<refname> property. The VS_DOTNET_REFERENCES property is typically used for Visual Studio managed references only.

Your set_property() command using the VS_DOTNET_REFERENCE_<refname> property was close, it just needs a small change:

set_property(TARGET ${project} PROPERTY VS_DOTNET_REFERENCE_Vector.CANoe.TFS "./lib/Vector.CANoe.TFS.dll")

The <refname> should refer to the DLL file name without the .dll file extension (ie only Vector.CANoe.TFS ). See this answer for another example.
