This should fix the Error: could not load cache BUG.
If there are already generated build files in the project directory, then if you execute the command cmake path/project in $OUT_DIR/build, cmake will not generate new build files in the $OUT_DIR/build directory.
cd /path/to/project
cmake .
# output `Build files have been written to: /path/to/project`
cd /path/to/build && cmake /path/to/project
# we expect the build files will be generated at current dir (/path/to/build)
# but unfortunately get `Build files have been written to: /path/to/project`
cd /path/to/build && cmake /path/to/project -B .
# output `Build files have been written to: /path/to/build`, that is right!
