Summary:                    Library not found when invoke find_library again
Description: 
I do a library search for my project:

find_library(
  ICU_LIBRARY
  NAMES icuuc cygicuuc cygicuuc32
  DOC "Libraries to link against for the common parts of ICU")

if(ICU_INCLUDE_DIR AND ICU_LIBRARY)
  set(ICU_FOUND 1)
else()
  set(ICU_FOUND)
endif()

This works for the first time but another call to cmake or a change in any
CMakeLists.txt file will unset ICU_FOUND.
