[CMake] FIND_PATH with multiple path in a single variable

[frederic heem]

Hi,
Here is the problem, pkgconfig is used to get the include path, for dbus, its 
value is "-I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include" and the 
variable name is DBUS_INCLUDE_DIR_SYSTEM. The following FIND_PATH fails to 
find the include files:
FIND_PATH(DBUS_INCLUDE_DIR dbus/dbus.h
  ${DBUS_INCLUDE_DIR_SYSTEM}
)

Is it a known issue ?
