c - Package gtk-engines-2 was not found in the pkg-config search path -

I am trying to compile the implementation of Rob Hayes of SIFT algorithm. I successfully installed OpenCiv2 2.1 and tested the installation with sample C programs provided. There was no error.

This code I was trying to compile was written using OpenCV 2.0. I successfully compiled and ran the exact code some time ago with OCV2.0. But now the compilation fails and it prints and prints it. I am using the file provided with the code.

 There is another problem in which Sekscore H is included. Can anyone tell me what is wrong here? Thank you in advance   
 
 
 My Ubuntu 10.10 box had the same problem.  
 I found what file was needed by build ("gdk / gdk.h") and saw that the gtk + -2.0 package (/usr/lib/pkgconfig/gtk+-2.0.pc) Usr / include / Gtk-2.0, which is relative to the required file. 
 
 I have edited the src / makefile and "pkg-config ... opencv gtk-engines-2" to "CPLGS and LIBS pkg-Pkg-config ... opencv gtk + -2.0" and this is my Designed for
