CMake is currently having lots of trouble if you have " "s
Gtk+ on Cygwin
pkg-config does not work well and cmake fails if GUI flag is turned on.
The emergency solution is editting yarp2/conf/FindGtkPlus.conf such as:
SET(GTKPLUS_LINK_FLAGS "-L/GTK/bin -lgtk-win32-2.0 -lglib-2.0 -lgdk-win32-2.0 -lgobject-2.0 -lgdk_pixbuf-2.0" CACHE INTERNAL "gtk+ link flags") SET(GTKPLUS_C_FLAGS "-I/GTK/include/atk-1.0 -I/GTK/include/pango-1.0 -I/GTK/include/gtk-2.0 -I/GTK/include/glib-2.0 -I/GTK/include/cairo -I/GTK/lib/gtk-2.0/include -I/GTK/lib/glib-2.0/include" CACHE INTERNAL "gtk+ include flags") SET(GTKPLUS_INCLUDE_DIR "/GTK/include/atk-1.0 /GTK/include/pango-1.0 /GTK/include/gtk-2.0 /GTK/inlcude/glib-2.0 /GTK/include/cairo /GTK/lib/gtk-2.0/include /GTK/lib/glib-2.0/include" CACHE INTERNAL "gtk+ include directory") IF (GTKPLUS_C_FLAGS) SET(GtkPlus_FOUND TRUE) ELSE (GTKPLUS_C_FLAGS)
/GTK is GTK_BASEPATH.
