尝试运行 cmake on Chipmunk 发生错误如何修复 cmake 文件？

Question

所以基本上我正在尝试在 linux mint 上构建 Chipmunk 物理库，它显然有一个 cmake 文件，我尝试运行但由于某些错误它没有完成，输出是

cmake ..
CMake Error at CMakeLists.txt:3 (cmake_policy):
  Policy "CMP0042" is not known to this version of CMake.

知道如何让 cmake 文件正常工作吗？

Answer 1

您的 CMake 版本太旧。 CMP0042 是在 CMake 2.8.12 中引入的。

你可以试试去掉CMakeLists.txt:3那一行，应该是make_policy(CMP0042)。但不能保证其他部分会按预期工作。
