执行测试COMPILER_HAS_DEPRECATED_ATTR -失败

Question

当我试图使用Visual Studio15 2017 Win64在CMAKE上配置一个项目时，我得到了这个错误：

The C compiler identification is MSVC 19.11.25547.0
The CXX compiler identification is MSVC 19.11.25547.0

我已经使用这个编译器生成了另一个项目，它仍然有效。以下是与新CMakeLists.txt相关的代码：

project(ms3d_td3)

cmake_minimum_required(VERSION 3.2.0)

add_subdirectory(ext/glfw)
add_subdirectory(ext/glbinding)

include_directories(ext/glfw/include)
include_directories(ext/glbinding/include)
include_directories(ext/eigen3)

if(APPLE)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -stdlib=libc++")
else()
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
endif()

set(SRC_FILES 
    src/main.cpp
    src/viewer.cpp
    src/viewer.h
    src/shader.cpp
    src/shader.h
    src/opengl.h)

add_definitions(-DDATA_DIR="${PROJECT_SOURCE_DIR}/data")

add_executable(ms3d_td3 ${SRC_FILES})

target_link_libraries(ms3d_td3 glfw ${GLFW_LIBRARIES} glbinding)

在Visual Studio2017下，我得到一个在EnableLanguage之后没有设置的CMAKE_C_COMPILER。我尝试手动将其设置为VisualStudio 2017编译器，但没有成功。有什么想法吗？

另一个人也有类似的问题，不久前通过升级Visual Studio解决了这个问题，所以我猜这是来自其他地方……：

Compiler failing on C++11 instructions in a Visual Studio project configured with cmake

谢谢!

要要求编译器支持[[decprecated]]属性，请使用target_compile_features并指定cxx_attribute_deprecated功能。例如：

add_executable(foo foo.cpp)
target_compile_features(foo PRIVATE cxx_attribute_deprecated)

如果您需要对此进行有条件的测试，以便配置一个头文件，请使用check_cxx_source_compiles。
