我刚刚在一个没有文件的测试目录下创建了一个三行 CMakeLists.txt，如下所示。我尝试了导出库路径等，但没有一个基本技巧起作用。如何使这项工作？

cmake_minimum_required(VERSION 3.6 FATAL_ERROR)
project(test CXX)
find_package(BLAS REQUIRED)

并运行它并得到以下错误。

如何使用 blas 制作 find_package 所需的工作在 cray 包装纸上？

Cray 编译器隐式链接 BLAS 和 LAPACK 库，因此它们通常不在命令行中给出。检测这种情况的功能已添加到 BLAS 的 CMake 3.13.0 中，并将添加到 LAPACK 的 CMake 3.16.0 中。

因此，如果您只对 BLAS 没问题，只需下载更新的 CMake 二进制 tarball。
