CMake无法找到已安装的SFML静态库问题求助

问题背景 #

我有一个依赖SFML库的C++项目，尝试使用CMake进行构建，当前CMakeLists.txt内容如下：

cmake_minimum_required(VERSION 3.16.3)
project(3D_Renderer_from_scratch)

set(CMAKE_CXX_STANDARD 17)

include_directories(headers source)

set(SFML_STATIC_LIBRARIES TRUE)

find_package(SFML COMPONENTS window graphics system)

set(SOURCES
        Main.cpp
        source/Application.cpp
        source/Box.cpp
        source/Camera.cpp
        source/FileReader.cpp
        source/KeyboardHandler.cpp
        source/Sphere.cpp
        source/Triangle.cpp
        source/Window.cpp
        source/World.cpp
        )

add_executable(executable ${SOURCES})

target_link_libraries(executable ${SFML_LIBRARIES} ${SFML_DEPENDENCIES})

执行cmake .命令后出现如下错误：

$ cmake .
-- Requested SFML configuration (Static) was not found
CMake Warning at CMakeLists.txt:10 (find_package):
  Found package configuration file:

    /usr/lib/x86_64-linux-gnu/cmake/SFML/SFMLConfig.cmake

  but it set SFML_FOUND to FALSE so package "SFML" is considered to be NOT
  FOUND.

注：SFML库已安装。

解决方案 #

方法一：改用动态链接（最简单有效） #

系统默认安装的SFML通常是动态库版本，并未附带静态库。只需注释或删除set(SFML_STATIC_LIBRARIES TRUE)这一行，让CMake自动使用动态库即可。同时建议在find_package中添加REQUIRED关键字，确保SFML库被正确找到：

修改后的CMakeLists.txt关键部分：

# 移除或注释掉这一行：set(SFML_STATIC_LIBRARIES TRUE)

find_package(SFML REQUIRED COMPONENTS window graphics system)

方法二：安装SFML静态库并指定路径 #

如果确实需要静态链接，需单独获取SFML静态库：

• 在Debian/Ubuntu系，可先检查系统是否已安装静态库文件：

  ls /usr/lib/x86_64-linux-gnu/libsfml-*.a
  

• 若未找到，可从SFML官网下载预编译的静态库包，或自行编译SFML时启用静态编译选项（编译时添加-DBUILD_SHARED_LIBS=OFF参数）。
• 获得静态库后，在CMake中指定其配置文件路径：

  set(SFML_STATIC_LIBRARIES TRUE)
  set(SFML_DIR "/path/to/sfml-static/cmake") # 替换为实际静态库的cmake目录
  find_package(SFML REQUIRED COMPONENTS window graphics system)
