如果您的应用程序与 GLUT兼容，并且它不使用freeglut的任何扩展名，那么搜索 GLUT 而不是 FREEGLUT :

If your application is GLUT-compatible, that it doesn't use any extension of freeglut, then it is better to search GLUT instead of FREEGLUT:

find_package(GLUT REQUIRED)

此命令所使用的查找"脚本已经包含在CMake发行版中，并且它也搜索freeglut.

"Find" script used by this command is already shipped into CMake distro, and it searches freeglut too.

(请注意，包含目录和链接库的命令变量分别是 GLUT_INCLUDE_DIR 和 GLUT_LIBRARY ).

(Note, that with that command variables for include directories and linking libraries are GLUT_INCLUDE_DIR and GLUT_LIBRARY correspondingly).

如果您的应用程序需要完全免费的胶粘剂(也就是说，使用其某些扩展名与其他GLUT实现不兼容)，则需要打包strong>和 FindFREEGLUT.cmake 脚本并相应地调整 CMAKE_MODULE_PATH 变量:

If your application requires exactly freeglut (that is, uses some of its extensions incompatible with other GLUT implementations), you need to ship your package with FindFREEGLUT.cmake script and adjust CMAKE_MODULE_PATH variable correspondingly:

# Assuming you have <source-dir>/cmake/FindFREEGLUT.cmake
list(APPEND CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake")
find_package(FREEGLUT REQUIRED)

您可以在网上找到现有脚本，也可以自己编写，例如

You may find existing script in the net, or write it by yourself, like here.

无论如何，如果您将freeglut安装在非系统位置，则需要向CMake提示.例如，通过调整 CMAKE_PREFIX_PATH .

In any case, if you have freeglut installed into non-system location, you need to hint CMake about that. E.g., by adjusting CMAKE_PREFIX_PATH.
