CACHE FORCE is not really a good style (I regret introducing it back when I
was there)
I guess you can do what you want to do simpler, with

IF(NOT MYSQL_PROJECT_NAME)
  SET(MYSQL_PROJECT_NAME "MySQL")
ENDIF()

I think you do not need to cache or document it.  It is probably better as
undocumented one-time setting  (if it should be at all) during initial cmake
run. Changing project name, e.g with cmake-gui after the initial CMake is
done sounds quite weird to be documented.
I'm curious why do you need that at all ..
