Lost ./configure

[Stephen Brown]

Hi All
I am attempting to compile gnucash 
After running the following commands in a cygwin terminal with all packages installed

cd /usr/src/git
rm -rfv gnucash
git clone https://github.com/Gnucash/gnucash.git
cd gnucash
git checkout master
git branch working-branch
git checkout working-branch

I am unable to see the ./configure program.

What am I doing wrong?

Yours Sincerely
Stephen Grant Brown
