[CMake] no space between include path

[frederic heem]

Hi,
Wireshark is being converted to cmake, when the dbus library is added, cmake 
doesn't add any space between the current source include path and the dbus 
path, and it adds the character "\" after each dbus path.
/usr/bin/gcc  -I/home/heefre/software/dbus/wireshark/build -I/home/heefre/software/dbus/wireshark -I/home/heefre/software/dbus/wireshark/wiretap -I/usr/lib/glib-2.0/include -I/usr/include/glib-2.0 -I/home/heefre/software/dbus/wireshark/-I/usr/include/dbus-1.0\ -I/usr/lib/dbus-1.0/include\ -I/usr/include/glib-2.0\ -I/usr/lib/glib-2.0/include   -DHAVE_CONFIG_H -D_U_="__attribute__((unused))" -o 
CMakeFiles/dumpcap.dir/capture_loop.o   -c /home/heefre/software/dbus/wireshark/capture_loop.c
If instead of adding the dbus library, another library is added, space are 
present.
Here is the wireshark CMakeLists.txt snippet:

set(PACKAGELIST ZLIB PCAP)

#D-Bus
option(ENABLE_DBUS	    "Build with D-Bus support" ON)
if(ENABLE_DBUS)
  set(PACKAGELIST DBUSGLIB ${PACKAGELIST})
  set(dumpcap_FILES ${dumpcap_FILES} dbus/wireshark-dbus-sniffer.c)
endif(ENABLE_DBUS)

foreach(PACKAGE ${PACKAGELIST})
	find_package(${PACKAGE})
	message(${PACKAGE}_FOUND)
	if (${PACKAGE}_FOUND)
		include_directories(${${PACKAGE}_INCLUDE_DIR})
		set(dumpcap_LIBS ${dumpcap_LIBS} ${${PACKAGE}_LIBRARIES})
	endif (${PACKAGE}_FOUND)
endforeach(PACKAGE)


here is the  FindDBUSGLIB.cmake
