Thank you for your reply,
Sorry, I am not a cmake expert. I cannot explain what CMakeCache.txt is
used for. What I can tell is that cmake users either edit CMakeCache.txt
directly to change values of options or use CMake GUI to build a project in
interactive mode, I am thinking whether we need qbs GUI in order to let
users build a project in interactive mode.
Why GUI is needed to let users build projects in interactive mode in cmake.
" Using CMake to build a project in non-interactive mode is a simple
process if the project does not have many options. For larger projects like
VTK, using ccmake, cmake -i, or CMakeSetup is recommended. This is because
as you change options in the CMakeCache.txt file, cmake may add new entries
to that file. It can be difficult to know when to stop the run cmake, edit
the cache file cycle without the aid of an interface."
