Are you wanting to build a closet with doors in a room where presently one does not exist?
Are you wanting to build a free-standing closet with doors so that it can be closed and the contents inside not seen?
Please post a picture of the space where you would like a closet so that we can see what you are starting with.
Make a frame to take the doors ( 2 x sides and a back) you have available and screw from the inside of frame through to the doors. Make three (3) levels of fixings. Then place frame on top of door to be used as base and secure in the same manner through the frame to the door. Last, but not least secure the roof door. You should now have a box or wardrobe shape without doors. Buy and fix wardrobe fixings and bar or buy Dowelling and jubilee clips or other suitable to form a hanging bar at top. Be sure it goes through the timber frame as the doors if hollow will not take the weight of many clothes. Use Clear polythene storage boxes at the bottom for jumpers/shirts etc. Decorate to your style and taste. Best wishes

Hi! maybe this will help
A frame and a way to secure the doors to the wall, etc. would be helpful. Boards running between the back of the doors can be screwed to the doors. Then screws can go through those boards and into the wall studs. I would probably put a piece of plywood on top of the doors to keep them sturdy. "L" brackets could secure the front of the doors to the floor. An alternative could be another board tying the doors together at the floor.
Here is some info to help you, just replace the wood from the wood from the doors.

Make it all shelfs
I would do something like this using the wall as the back and then fasten door to the wall to create the side walls. Then I would add shelves and bars inside like they do. https://abeautifulmess.com/creating-an-open-closet-system/
