Performing Test COMPILER_HAS_DEPRECATED_ATTR - Failed - c++

Question

I'm currently getting this error while trying to configure a project on CMAKE using Visual Studio 15 2017 Win64:
The C compiler identification is MSVC 19.11.25547.0
The CXX compiler identification is MSVC 19.11.25547.0

I've used this compiler to generate another project and it still works.
Here is the code relevant to the new CMakeLists.txt:
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)
Under Visual Studio 2017 I get a CMAKE_C_COMPILER not set after EnableLanguage. I tried to set it manually to the VisualStudio 2017 compiler but no success. Any ideas?
Another person had a similar problem and solved it by upgrading Visual Studio a while ago so I'm guessing this is coming from somewhere else... :

Thanks!

To require compiler support for the [[decprecated]] attribute, use target_compile_features and specify the cxx_attribute_deprecated feature. For example:
add_executable(foo foo.cpp)
target_compile_features(foo PRIVATE cxx_attribute_deprecated)
If you need to conditionally test for this so that you can configure a header file, use check_cxx_source_compiles.
