CMake无法确定目标的链接器语言：azurestorage错误 [英] CMake can not determine linker language for target: azurestorage error

问题描述

我是C ++编程的新手，在使用CMake将azure-storage-cpp存储库添加到VS解决方案时遇到了一些麻烦。

I'm very new to C++ programming and having some trouble using CMake to add the azure-storage-cpp repository to my VS solution.

这里是构建错误，当我尝试构建azure存储项目时进入VS。

Here is the build error I am getting in VS, when I attempt to build the azure storage project.

CMake无法确定目标程序的链接器语言：azurestorage

CMake can not determine linker language for target: azurestorage

这是我的CMake条目：

Here is my CMake entry:

ExternalProject_Add( azurestorage
  PREFIX azurestorage
  GIT_REPOSITORY https://github.com/Azure/azure-storage-cpp.git
  GIT_TAG master
  SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/../azurestorage
  SOURCE_SUBDIR Microsoft.WindowsAzure.Storage)

我尝试添加 SET_TARGET_PROPERTIES（azurestorage PROPERTIES LINKER_LANGUAGE CXX）到我的CMakeList.txt文件中，但没有帮助。我还在其他论坛上读过，回购协议需要在根目录中有一个.cpp和.h文件，CMake才能知道哪种语言。但是，由于azure-storage-cpp仓库不是我的仓库，因此我无法添加此类文件。

I tried adding SET_TARGET_PROPERTIES(azurestorage PROPERTIES LINKER_LANGUAGE CXX) to my CMakeList.txt file but it doesn't help. I've also read on other forums that the repo needs to have a .cpp and .h file in the root directory for CMake to know which language. However since the azure-storage-cpp repo isn't mine, I don't have the ability to add such files.

我在Windows10上使用VS2015

I'm using VS2015 on Windows10

我在做什么错？感谢所有帮助。

What am I doing wrong? Any and all help is appreciated.

推荐答案

我已经尝试了您的示例，相关的错误消息更多CMake的输出：

I've given your example a try and the relevant error message is more to the top of CMake's output:

-- Unsupported Build Platform.

因此，如果要添加它，请不要使用 ExternalProject_Add（） 。库中包含的 CMakeLists.txt 用于 Unix / Linux / OSX 。

So if you want to add it, don't use ExternalProject_Add(). The library's included CMakeLists.txt is for Unix/Linux/OSX.

但是它带有VS2015的现有 .vcproj ，您可以使用 include_external_msproject（） ：

But it comes with an existing .vcproj for VS2015 which you can include into your project with include_external_msproject():

find_package(Git REQUIRED)
execute_process(
    COMMAND "${GIT_EXECUTABLE}" clone https://github.com/Azure/azure-storage-cpp.git
)
set(NUGET_EXECUTABLE "${CMAKE_CURRENT_BINARY_DIR}/azure-storage-cpp/tools/NuGet.exe")
execute_process(
    COMMAND "${NUGET_EXECUTABLE}" restore "azure-storage-cpp/Microsoft.WindowsAzure.Storage.v140.sln" 
)
include_external_msproject(
    azurestorage 
    "azure-storage-cpp/Microsoft.WindowsAzure.Storage/Microsoft.WindowsAzure.Storage.v140.vcxproj"
)
