Which instructions? I looked for "cmake -" in the source tree, and all
documentation in docbook/ suggest a build dir next to the source dir.
The only example that creates a build dir in the source tree is the
Gitlab CI configuration.

The general recommendation is to do an out-of-tree build (where the
build directory is not equal to the source tree). This could either be
in-tree (mkdir build && cd build) or in a different location (mkdir
/tmp/build && cd /tmp/build).

Personally I use both approaches: my main development has a source tree
symlinked at /tmp/wireshark and a build directory at /tmp/wsbuild. When
building from a temporary git worktree, I usually create a build
directory within this tree for convenience:

    # Run from source directory, create a new source directory which
    # shares the same git repository:
    git worktree add /tmp/wireshark-2.4 master-2.4
    cd /tmp/wireshark-2.4
    # update master-2.4 branch
    git pull
    mkdir build && cd build && cmake -GNinja .. (other options here)
    # when done, go back to original source tree and wipe temp dir
    cd /tmp/wireshark
    rm -r /tmp/wireshark-2.4
    git worktree prune -v
Kind regards,
