Omr: AppVeyor builds are failling due to an error running cmake

AppVeyor builds seem to be failing consistently with the following output:

to me, it looks like we're losing a space before the dot at the end of this line:

cmake -Wdev -G "Visual Studio 11 2012" -DOMR_ENV_DATA32=ON -Ccmake\caches\Appveyor.cmake.

But it's been this way in the appveyor config for ~2 years (since https://github.com/eclipse/omr/commit/d475533510163216fe45bca515a6759416aa0425), so that's maybe not the issue.

Cmake was updated to 3.13 yesterday (feb 11 2019). Check out the release notes:

CMake now checks that at least one of the source or binary directory is specified when running CMake

I'll leave it up to you to open the PR 😁

How about you open the PR and I merge it :grin:
