Some of the variables like CFLAGS, CXXFLAGS, LDFLAGS are not empty.
It is not possible to build ClickHouse with custom flags.
These variables can be set up by previous invocation of some other build tools.
You should cleanup these variables and start over again.
Run the `env` command to check the details.
You will also need to remove the contents of the build directory.
Note: if you don't like this behavior, you can manually edit the cmake files, but please don't complain to developers.")
