message when ACE is missing is cryptic

[paulfitz]

Attempting to configure YARP using CMake on a system without ACE gives this message:

CMake Error at conf/FindACE.cmake:75 (file):
  file STRINGS file "/root/cvs/yarp/ACE_INCLUDE_DIR-NOTFOUND/ace/Version.h"
  cannot be read.
Call Stack (most recent call first):
  conf/YarpAceCheck.cmake:18 (find_package)
  CMakeLists.txt:49 (include)
CMake Error at conf/FindACE.cmake:91 (message):
  Include file ace/Version.h does not exist
Call Stack (most recent call first):
  conf/YarpAceCheck.cmake:18 (find_package)
  CMakeLists.txt:49 (include)
-- Configuring incomplete, errors occurred!

It might be clearer to state that ACE has not been found and fail, or configure to compile without ACE.

Should be fixed by commit 967ddfa
Can you please check?
