Or, if no such header can be found, define the "uchar" typedef
yourself - before including openCVApp.h:

typedef unsigned char uchar;
// ...
#include "openCVApp.h"

Even if the header with the "uchar" typedef is eventually found and
included - having an extra "uchar" typedef in the same translation
unit should not be a problem. A C++ program is free to define the same
typedef, multiple times within a single scope - provided that the
typedef is defined the same way each time.
