I had a project which was not using cloudbees folder plugin.

• code was commited in f:\jenkins\workspace\myproject\git-code
• code was configured in and compiled in the following folder: f:\jenkins\workspace\myproject\build

I add a "Project" cloudbee folder in jenkis and moved myproject into this folder.
Now:

• code is commited in f:\jenkins\workspace\Project\myproject\git-code
• but code is configured in and compiled in the old folder: f:\jenkins\workspace\myproject\build

So, I use the git pluging to commit the source code and the name of the folder has been added into the cloned directory name, but the folder name has not been added to the path where the build script is launched (I use "execute a batch script" to start a cmake commande and the nmake to start the build).
