cray CC wrapper cmake find_package blas

Question

i刚刚创建了一个三行cmakelists.txt，如测试目录下面没有任何文件。我尝试了导出lib路径等，但没有任何基本技巧可行。如何使这项工作？

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

并将其作为并收到以下错误。

如何在cray包装纸上使用Blas进行Find_package？

Answer 1

cray编译器隐式链接blas和lapack库，因此通常在命令行上不给出它们。检测到这种情况的能力已添加到Blas的Cmake 3.13.0中，并将添加到Cmake 3.16.0的Lapack中。

因此，如果您只能使用Blas，请下载较新的Cmake二进制tarball。
