无法为编译 SFML 项目创建 cmake 规则

Question

我有 build/cmakelists.txt 文件：

cmake_minimum_required (VERSION 2.8)
project(Tetris)
include_directories(
    "headers"
)
set(SFML_DEPENDENCIES)
set(SFML_DEPENDENCIES ${SFML_SYSTEM_DEPENDENCIES} ${SFML_DEPENDENCIES})
set(SFML_DEPENDENCIES ${SFML_GRAPHICS_DEPENDENCIES} ${SFML_DEPENDENCIES})
set(SFML_DEPENDENCIES ${SFML_WINDOW_DEPENDENCIES} ${SFML_DEPENDENCIES})
set(CMAKE_CXX_COMPILER /usr/bin/g++-5)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -Wall -g")
set(EXECUTABLE_NAME "tetris")
file(GLOB SOURCES *.cpp)
add_executable(${EXECUTABLE_NAME} ${SOURCES})
target_link_libraries(${EXECUTABLE_NAME} ${SFML_LIBRARIES})

当我运行 cmake ..＆amp;＆amp;make 我有一个消息的屏幕，说我不包括sfml库：

undefined reference to `sf::VertexArray::operator[](unsigned long)'
undefined reference to `sf::Keyboard::isKeyPressed(sf::Keyboard::Key)'

等等。我还尝试将标志包括到cmake_cxx_flags变量： -LSFML-GRAPHICS -LSFML-WINDOW -LSFML-SYSTEM 它也不起作用。但是，如果我直接从控制台运行G ，则所有这些都可以很好地编译：

g++-5 --std=c++11 -Wall main.cpp Game.cpp Window.cpp Board.cpp -lsfml-graphics -lsfml-window -lsfml-system

我使用Linux Mint(如果有任何差异(。

您需要查找SFML软件包的位置，并添加包括目录和链接。

在您的cmakelists.txt：
更改此行：

target_link_libraries(${EXECUTABLE_NAME} ${SFML_LIBRARIES})

：

# Detect and add SFML
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake_modules" ${CMAKE_MODULE_PATH})
#Find any version 2.X of SFML
#See the FindSFML.cmake file for additional details and instructions
find_package(SFML 2 REQUIRED system window graphics)
if(SFML_FOUND)
  include_directories(${SFML_INCLUDE_DIR})
  target_link_libraries(${EXECUTABLE_NAME} ${SFML_LIBRARIES})
endif()

对于SFML V1，更改find_package行：

find_package(SFML 1 REQUIRED system window graphics)
