[oe] Build error while using bitabake linphone

[vivek tambakad]

Hi
       When i am compiling linphone it shows the following GTK error.

 checking for LIBGTK... configure: error: Package requirements (gtk+-2.0 >=
2.4.0 gthread-2.0) were not met:
|
| No package 'gtk+-2.0' found
|
| Consider adjusting the PKG_CONFIG_PATH environment variable if you
| installed software in a non-standard prefix.
|
| Alternatively, you may set the environment variables LIBGTK_CFLAGS
| and LIBGTK_LIBS to avoid the need to call pkg-config.
| See the pkg-config man page for more details.

| FATAL: oe_runconf failed

Please tell what changes i have to make in linphone bitbake file so that it
works fine.
