QGroundControl build issues under Windows 10 with VS 2015

Greetings,

I am attempting to build QGC. I am using Windows 10 with VS 2105 and QC Creator.
I used GIT for Windows to obtain the source.

When I run the command:
git clone https://github.com/mavlink/qgroundcontrol.git --recursive

A directory is created and it appears to download all of the needed source files.

However, I am not 100% certain that I have all of the needed source files, because the instructions say
“Update submodules (required each time you pull new source code):”

When I run the command:
git submodule update

The following error is displayed:
fatal: not a git repository (or any of the parent directories): .git

I don’t know why the command does nothing, what am I missing?

The other issue is with QC Creator, when I build the project I the error:
Error: dependent ‘release\qgc_pt_PT.qm’ does not exist.
is returned

Any ideas, comments, thoughts would be greatly appreciated.
