前置条件：已安装了 VS2012，IVF2013。
需要安装 lapack 等库文件来实现科学计算。
实现步骤：Lapack 库需要使用 Cmake，因此需要先安装好 Cmake！
一、Cmake 的安装
过程可参考这里。
To build LAPACK libraries under Windows?
You will need to install CMAKE on your machine and please refer to the build section .
Cmake 版本（cmake-3.18.4-win64-x64.msi），可以从这里下载。
二、Lapack 的安装
（注：Lapack 库在 Win10下的安装和使用样例，可以参见这篇博客 https://www.cnblogs.com/panscience/p/4966404.html）
lapack-3.9.0.tar.gz 的下载地址位于这里，可以参考 Lapack 网站 上的介绍，即，“LAPACK for Windows”一节的介绍：
LAPACK for Windows LAPACK is built under Windows using Cmake the cross-platform, open-source build system. The new build system was developed in collaboration with Kitware Inc. A dedicated website (http://icl.cs.utk.edu/lapack-for-windows/lapack) is available for Windows users. You will find information about your configuration need.
安装和样例调试的所有步骤，见这里，即，“Easy Windows Build”一节的介绍：
Easy Windows Build
Build Instructions for LAPACK 3.9.0 for Windows with Visual Studio
Requirements: Visual Studio, Intel C and Fortran Compilers, CMAKE 2.8.12
- Download the lapack.tgz from the netlib website and unzip.
- Download CMAKE and install it on your machine.
- Open CMAKE
- Point to your lapack-3.9.0 folder as the source code folder
- Point to a new folder where you want the build to be (not the same is better)
- Click configure, check the install path if you want to have the libraries and includes in a particular location.
- Choose Visual Studio Solution.
- You will have to click "Specify native compilers" and indicate the path to the ifort compiler. On my machine, it is "C:/Program Files (x86)/Intel/Compiler/11.1/048/bin/ia32/icl.exe".
- You may have to click again configure until everything becomes white
- Click generate, that will create the Visual Studio Solution and you are done.
- Close CMAKE
- Look in your "build" folder, you have your LAPACK Visual Studio Solution, just open it.
- Build the "ALL_BUILD" project, it will build the solution and create the libraries
- Build the "INSTALL". This will put the libraries and include in your install folder.
- Build the "RUN_TESTS". The BLAS and LAPACK testings will be run.
注意事项：
需要注意的是，下载的 lapack 文件夹中，需要在 CMake 开始前，执行两步修改：
（1）复制 make.inc.example 文件，并重命名为 make.inc；
（2）Lapack 需要用到 Blas 库，因此系统有无 Blas 库对应着两种不同的做法。
如果系统已经有了 Blas 库，或者说你想要用自己的 Blas 库，你需要修改 make.inc 里的 USEXBLAS 、 XBLASLIB 和 XBLASLIB 三个变量，修改完直接Make就行了。
如果系统没有 Blas 库，Lapack 源码里自己带了一个，可以直接用。那么保持 make.inc 里的设置不变，打开 Makefile，把 Blas 库加到编译目标里，就是 lib 参数编程：
# lib: lapacklib tmglib # 修改前
lib: blaslib lapacklib tmglib # 修改后
