Yes, it should. Probably you're calling a third party (cygwin ?)
pkg-config instead of the executable provided with the GTK+
distribution. Alternatively, you chose two different installation
directories for GTK+ and gtkmm. In this case, you have to explicitly set
the PKG_CONFIG_PATH environment variable, something like

PKG_CONFIG_PATH=C:\gtkmm\lib\pkgconfig;C:\GTK\lib\pkgconfig
