c++ - CMake:在 Windows 上找不到编译器

Question

当我运行它时:cmake -G "Visual Studio 15 2017 Win64"

我有这个输出:

-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:2 (project):
  No CMAKE_C_COMPILER could be found.

CMake Error at CMakeLists.txt:2 (project):
  No CMAKE_CXX_COMPILER could be found.

-- Configuring incomplete, errors occurred!

这是我的CMakeLists(我已经删除了例子中无用的东西)

cmake_minimum_required(VERSION 3.4)
project(type)

option(BUILD_CLIENT "Build Client" ON)
option(BUILD_SERVER "Build Server" ON)

set(CLIENT_NAME "type_client")
set(SERVER_NAME "type_server")

set(LIB_LINKS "-ldl -lpthread")

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}")

set(CLIENT_SOURCE_FILES

    include_directories(${INC_DIR_DLLOADER}/linux)

    set(SFML_ROOT "dependancies/SFML-2.4.1")
endif()

include_directories(${SFML_INCLUDE_DIR})

if(BUILD_CLIENT)
  add_executable(${CLIENT_NAME} ${CLIENT_SOURCE_FILES})
  target_link_libraries(${CLIENT_NAME} ${SFML_LIBRARIES} ${LIB_LINKS})
endif()

if(BUILD_SERVER)
    if(WIN32)
        add_executable(${SERVER_NAME} ${SERVER_SOURCE_FILES}
                ${SERVER_SOURCE_FILES_SYSTEMS} ${SERVER_SOURCE_FILES_WIN})
        target_link_libraries(${SERVER_NAME} -lws2_32)

    elseif(UNIX)
        add_executable(${SERVER_NAME} ${SERVER_SOURCE_FILES}
                ${SERVER_SOURCE_FILES_SYSTEMS} ${SERVER_SOURCE_FILES_LINUX})
        target_link_libraries(${SERVER_NAME} ${LIB_LINKS})
    endif()
endif()

我用 Visual Studio 安装了 C++ 编译器，所以我不明白为什么没有检测到编译器。

尝试用 cmake -G "Visual Studio 14 2015" 编译
