How to install plyvel on wondows

I use winodws10 64bit, so target is x86_64

Build Leveldb

• DL msys2-x86_64-20180531.exe https://www.msys2.org/
• DL cmake-3.14.2-win64-x64.msi https://cmake.org/download/
• DL leveldb-master https://github.com/google/leveldb
• make build folder
• execute on build folder: "C:\Program Files\CMake\bin\cmake.exe" -G "MSYS Makefiles" ..
• check1 libleveldb.a
• check2 leveldb, include many header files

Build plyvel

• DL plyvel-master https://github.com/wbolster/plyvel
• make include folder and copy libleveldb.a and leveldb
• rewrite setup.py

extra_compile_args = ['-Wall', '-g', '-x', 'c++', '-std=c++11', '-DMS_WIN64']

ext_modules = [
    Extension(
        'plyvel._plyvel',
        language='c++',
        include_dirs=['include'],
        library_dirs=['include'],
        sources=['plyvel/_plyvel.pyx', 'plyvel/comparator.cpp'],
        libraries=['leveldb'],
        extra_compile_args=extra_compile_args,
    )
]

• open MSYS2 terminal and execute: "path\to\python.exe" setup.py bdist_wheel
• check wheel file in dist folder

Install plyvel

• install by wheel
• pip install plyvel-1.0.5-cp36-cp36m-win_amd64.whl

Thank you for writing this up. However I am having a little problem. I navigate to the build folder and execute
"C:\Program Files\CMake\bin\cmake.exe" -G "MSYS Makefiles" ..
But I get the following error

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

msys is installed in the C drive
cmake is installed
msys directory is in PATH

Help?
