In 837f637cf51 (meson.build: correct setting of GIT_EXEC_PATH, 2025-05-19) we have fixed how we configure GIT_EXEC_PATH in some cases. It was reported [1] though that this causes a new issue when overriding libexecdir with `-Dlibexecdir=`:

    $ meson setup -Dprefix=/tmp/git -Dlibexecdir=libexec-different
    $ meson install
    $ /tmp/git/bin/git --exec-path
    /tmp/git/libexec-different
    $ /tmp/git/bin/git daemon
    git: 'daemon' is not a git command. See 'git --help'.

While we correctly propagate the libexecdir to Git's GIT_EXEC_PATH, we forgot to append 'git-core'. Consequently, it cannot find its binaries anymore.

Fix this issue by appending 'git-core' to libexecdir. With this, things work as expected:

    $ meson install
    $ /tmp/git/bin/git --exec-path
    /tmp/git/libexec-different/git-core
    $ /tmp/git/bin/git daemon -h
    ...
