After you've started the next mission, go right until you'll notice a building. Then hold down the left mouse button, and you should see a line made of dots - this line shows the distance in which you can make a jump. Jump to the left side of the building and climb on the roof.
Then jump down to the bottom of the right side of the building and go inside through the open door. Use the elevator to get to the first floor and in the room on the right; you will see an optional task that looks like a laptop (shown in the picture above).
Pick it up, and then go back to the elevator and make your way to the top floor. Run to the end of the room on the raid and hack the main computer.
After that, jump through the window on the right and run to the exit.
