Obj_location
(Project Properties window)
*.prj\COMPILE\Obj_Location
This setting defines the location for object files relative to sources for this build.
By default, object files are stored in the project base directory, local. However, you can use this setting to store these files in a different location.
This is used in conjunction with the Obj_sub setting.
Specified subdirectories are created automatically if they do not exist.
