我不明白的 CMake 错误

Question

我正在使用 CMake 编译一个项目。这是我的来源的路径： https://github.com/Ro6afF/Snake 。当我输入这个

cd build && cmake ..

它打印这个：

CMake Error: Could not find cmake module file: CMakeDetermineSnakeCompiler.cmake
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_Snake_COMPILER_ENV_VAR
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_Snake_COMPILER
CMake Error: Could not find cmake module file: /home/asd/snake/build/CMakeFiles/3.5.0/CMakeSnakeCompiler.cmake
CMake Error at CMakeLists.txt:3 (Project):
  No CMAKE_Snake_COMPILER could be found.

  Tell CMake where to find the compiler by setting the CMake cache entry
  CMAKE_Snake_COMPILER to the full path to the compiler, or to the compiler
  name if it is in the PATH.


CMake Error: Could not find cmake module file: CMakeSnakeInformation.cmake
CMake Error: CMAKE_Snake_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

你能解释一下如何解决这个错误吗？提前致谢！

Answer 1

您错误地使用了project命令：

PROJECT(OpenGL Snake)

space 充当分隔符。这意味着项目名称是 OpenGL，语言是 Snake。 CMake 不知道这样的语言。

将代码更改为

PROJECT(OpenGL_Snake)
