appveyor.yml failures - change to "mkdir" on line 37

appveyor.yml

Problem: When the directory exists, appveyor throws an error and does not build. I've been whipsawed by this problem. Also when the directory does not exist, you need the mkdir build command. This seems to work. I have not tried relative paths, maybe that will work, but my reading showed this works, and it does, but would be interested in better solutions (would a simple "rmdir build" work without throwing an error, before mkdir?).

before_build:
  - cd c:\project\squiddio_pi
#  - mkdir -p build
  - if not exist "c:\project\squiddio_pi\build" mkdir c:\project\squiddio_pi\build
  - cd build

Found this line in Alec Leamas PR

rm -rf build && mkdir build && cd build

Looks pretty good to me, maybe it will work with appveyor.yml

That works!

before_build:
  - cd c:\project\squiddio_pi
#  - mkdir -p build
#  - if not exist "c:\project\squiddio_pi\build" mkdir c:\project\squiddio_pi\build
  - rm -rf build && mkdir build && cd build
#  - cd build

Merged, builds.
