VCPKG 消息冲突

Question

关于我的系统上是否存在 Ninja 的消息相互矛盾。

我看到它存在/不存在。你知道这是什么原因吗？难道是我的端口文件有问题？

-- Found external ninja('1.10.2').
-- Configuring x64-win-llvm-static-md
-- Building x64-win-llvm-static-md-dbg

CMake Error: CMake was unable to find a build program corresponding to "Ninja".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build

CMake 无法找到 Ninja 的最后一个错误是“级联”错误，当向 CMake 提供 vcpkg 工具链文件并且任何 vcpkg 步骤失败时，就会发生这种情况。是的，这很令人困惑，真正的原因通常在 vcpkg 输出中进一步列出。 您还没有发布完整的输出，但有线索的行如下：

构建失败的端口在上面 URL 中的方括号中：

[kassert]

。您有可能能够确定 通过检查

$VCKPG_ROOT/buildtrees/kassert/*.log

中的日志文件来了解构建失败的性质。我个人会从该目录中的

install-x64-mingw-static-dbg-out.log

开始。
