Summary0013293: INTERNAL: Cache value overwritten without a FORCE option set.
DescriptionOn INTERNAL type, the cache value is overwritten without a FORCE option set.
Steps To Reproducecmake_minimum_required(VERSION 2.8.8)

#
# From CMake 2.8.8 documentation:
#
# If <type> is INTERNAL, then the <value> is always written into the cache, replacing any values
# existing in the cache. If it is not a cache variable, then this always writes into the current
# makefile. The FORCE option will overwrite the cache value removing any changes by the user.
#

How is this a bug? The documentation you quote explains exactly the behavior you report. This is by design and has always been the case since CMake started. INTERNAL entries are not available for the user to edit in the GUI so there is no need to preserve user-set values. Please post to the mailing list instead of the issue tracker if you have further questions.
