新手使用，应该很简单，有经验的朋友麻烦指点一下。

我编译OpenBLAS时出现的问题。
按照这个说明一步一步的操作。
https://github.com/xianyi/OpenBLAS/wiki/How-to-use-OpenBLAS-in-Microsoft-Visual-Studio

输入完这个指令后，运行
cmake .. -G "Ninja" -DCMAKE_CXX_COMPILER=clang-cl -DCMAKE_C_COMPILER=clang-cl -DCMAKE_Fortran_COMPILER=flang -DBUILD_WITHOUT_LAPACK=no -DNOFORTRAN=0 -DDYNAMIC_ARCH=ON -DCMAKE_BUILD_TYPE=Release

就出现下面的错误提示了。看起来像是gfortran 这个编译程序找不到路径，或者没有指定文件位置。

-- GEMM multithread threshold set to 4.
CMake Deprecation Warning at D:/SpecialProgram/Anaconda2/Library/share/cmake-3.11/Modules/CMakeForceCompiler.cmake:97 (message):
The CMAKE_FORCE_Fortran_COMPILER macro is deprecated. Instead just set
CMAKE_Fortran_COMPILER and allow CMake to identify the compiler.

CMake Error at cmake/f_check.cmake:30 (enable_language):
The CMAKE_Fortran_COMPILER:

is not a full path and was not found in the PATH.

Tell CMake where to find the compiler by setting either the environment
variable "FC" or the CMake cache entry CMAKE_Fortran_COMPILER to the full
path to the compiler, or to the compiler name if it is in the PATH.

接下来，安装gfortran,
输入 conda install -y gfortran
但是又出现下面的提示，似乎找不到gfortran， 我是不是走错方向了？ 哪位大哥指点指点 ，非常感谢
