Error compiling blank project opencv 4.8.1 (Fedora 39)

[PaoloMolinari]

I have got an error compiling even a blank project with ofxCv activated in a fedora 39 fresh install with opencv 4.8.1. ofxOpenCv work find by the way. The problem is the following:

openFrameworks/addons/ofxCv/src/ofxCv.h:23:
./openFrameworks/addons/ofxCv/libs/ofxCv/include/ofxCv/Tracker.h:
128:28: error: expected unqualified-id before ‘)’ token
  128 |                 Tracker<T>()
      |       
```                     ^

which makes reference to this part of the file Tracker.h:

	```
public:
		Tracker<T>()
		:persistence(15)
		,curLabel(0)
		,maximumDistance(64) {
		}

It used to work in Fedora 38. Any idea about what could it be?
