Opengl 使用CMake查找SFML（Ubuntu 18.04）

我正在尝试开始使用opengl。我首先遵循了一个安装opengl的方法，编译了自己的示例，效果很好。然后，我安装了从中建议的必备库

然后，我从他们的网站上获取了一个示例，并尝试使用CMake进行编译。它在

find_package

步骤失败

cmake_minimum_required (VERSION 3.10)

################
# Project
################ 
project (opengl_test)

################
# Packages
################
find_package(OpenGL REQUIRED)
find_package(GLUT REQUIRED)
find_package(SFML REQUIRED system window graphics network audio)

OpenGL和GLUT被正确地找到和链接，并且只需要这两个文件就可以按预期编译和运行。但是，SFML查找不起作用

  By not providing "FindSFML.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "SFML", but
  CMake did not find one.

  Could not find a package configuration file provided by "SFML" with any of
  the following names:

    SFMLConfig.cmake
    sfml-config.cmake

  Add the installation prefix of "SFML" to CMAKE_PREFIX_PATH or set
  "SFML_DIR" to a directory containing one of the above files.  If "SFML"
  provides a separate development package or SDK, be sure it has been
  installed.

我怀疑我必须提供一个到SFML的路径。我知道在StackOverflow上有大约30篇关于这个主题的帖子。我尝试了其中的几个，但都不起作用，错误仍然是一样的。

您的

/usr

树中是否有

SFMLConfig.cmake

？libsfmldev应该在那里放一个。我设法用

列表（附加CMAKE\u MODULE\u PATH）/usr/share/SFML/CMAKE/Modules）解决了这个问题。我肯定我以前试过10次，但都没用。我需要习惯在调试时删除临时cmake文件。但是，现在问题解决了：）一个稍微简单的方法是设置
CMAKE\u PREFIX\u PATH=/usr/share/SFML
谢谢，我会试试。最终，我想让它独立于平台，也许可以使用
find_path
，但现在它可以工作了，我应该专注于实际的程序：D
