Thanks for the issue report. Could you please provide steps to reproduce this? A list of command or Dockerfile would do. I tried to build on the debian:trixie docker image but could not figure out how to install the libpcre3-dev dependency.

[ksqrtr]

I've installed it manually since Debian 13 doesn't provide one:

export LEGACY_PCRE_VERSION="8.45"
export TMP=$(mktemp --directory)

cd $TMP

wget https://deac-fra.dl.sourceforge.net/project/pcre/pcre/${LEGACY_PCRE_VERSION}/pcre-${LEGACY_PCRE_VERSION}.tar.bz2
tar xf pcre-${LEGACY_PCRE_VERSION}.tar.bz2
cd pcre-${LEGACY_PCRE_VERSION}
./configure --prefix=/usr/local
make -j $(nproc)
make install

cd /tmp
rm -rf $TMP

Also see #12442

[cmcfarlen]

Could you please share your cmake definitions you used to configure the build? That would help reproduce this. Thanks!

Dockerfile.txt

Here is a Dockerfile to reproduce issue, hope this helps.

I was finally able to reproduce this. CMAKE_BUILD_TYPE=RelWithDebInfo was the key.

I found that the issue is not new on 10.1.0. I see the same warning on 10.0.x as well. We should fix this but I don't think it's a blocker for 10.1.0 release.
