Cannot find file: QtBitcoinTrader_Desktop.pro.
Any chance you already cloned the git repository? If not then you would need to do that. I might post some code for it tomorrow it's on a different computer so I'm too lazy to post it now.
Edit:
git clone https://github.com/JulyIGHOR/QtBitcoinTrader/tree/testing
That will put the whole project in whatever folder you are in when you run it making a sub folder called QtBitcoinTrader. Once you have run that once the following code will grab the current version. I'm sure you don't need the last 4 lines but it should work great. I have it in a .sh file.
git fetch --all
git merge
git checkout master
cd src
qmake QtBitcoinTrader_Desktop.pro
make
make install

Just as a really stupid question did you actually install git? You can't navigate to that page directly. You can go to
https://github.com/JulyIGHOR/ then navigate from there but it isn't so easy to get all of the files required to actually make the project.
