[CMake] Strange behaviour of FindCurses.cmake (and cmake 2.6.0?)

[Christian Ehrlicher]

Hi,

when curses is searched twice, the second search fails:

---------------------8<----------------
message(STATUS "CURSES_HAVE_CURSES_H: ${CURSES_HAVE_CURSES_H}")
message(STATUS "CURSES_INCLUDE_PATH:  ${CURSES_INCLUDE_PATH}")
FIND_PACKAGE(Curses REQUIRED)
message(STATUS "CURSES_HAVE_CURSES_H: ${CURSES_HAVE_CURSES_H}")
message(STATUS "CURSES_INCLUDE_PATH:  ${CURSES_INCLUDE_PATH}")
FIND_PACKAGE(Curses REQUIRED)
message(STATUS "CURSES_HAVE_CURSES_H: ${CURSES_HAVE_CURSES_H}")
message(STATUS "CURSES_INCLUDE_PATH:  ${CURSES_INCLUDE_PATH}")
---------------------8<----------------

gives this output:

---------------------8<----------------
-- CURSES_HAVE_CURSES_H:
-- CURSES_INCLUDE_PATH:
-- Found Curses: /usr/lib64/libncurses.so
-- CURSES_HAVE_CURSES_H: /usr/include/curses.h
-- CURSES_INCLUDE_PATH:  /usr/include
CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:52 (MESSAGE):
  Could NOT find Curses
Call Stack (most recent call first):
  /usr/share/cmake/Modules/FindCurses.cmake:104 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:8 (FIND_PACKAGE)
---------------------8<----------------

Any ideas what's going wrong here? I think it worked fine with 2.4.8 but can't test it atm.
