ninja install fails.

[PhilipDeegan]

with a script like

#!/usr/bin/env bash
set -exu
CWD="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )" && cd $CWD

(
    cd $CWD
    rm -rf build && mkdir build && cd build
    cmake -G Ninja -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_INSTALL_PREFIX=$PWD ../flann
    ninja && ninja install
)

then during ninja install after compilation

Installed /opt/py/python-3.11.4/lib/python3.11/site-packages/flann-1.9.2-py3.11.egg

  directory.

FAILED: CMakeFiles/install.util 

adding -DBUILD_EXAMPLES=OFF to the cmake config command resolves this for me.

I don't see this on github actions strangely

a bit more digging, seems I was using cmake 3.28 from pip install which has this issue, whereas cmake via apt install is for me, cmake 3.25.1, which does not have this issue
