I believe the word used was "reproducible" not "reliable" -- and I think he
was talking about the fact that it is not reproducible because it depends on
human interaction. Other than the human sitting at the keyboard, I have
found ccmake (and *all* of the cmake executables) to be quite reliable.
The thing that is confusing you about the CMAKE_INSTALL_PREFIX value is
something that it takes everyone a while to get their heads around... The
*cached* value (that you see in the GUI) is not the same as the local
variable value in the CMakeLists.txt file. When you use set(var "value") in
a CMakeLists.txt file using a variable name that is also in the cache, you
are only affecting the local value in the CMakeLists.txt file, not the cache
value.
And when you print it out (and when CMake generates make files) it is the
local value that matters, not the cached value that you see in the GUI.
Once you get your head around that concept, I think you'll find ccmake is
quite reliable. :-)
