It is unclear why changing:

cmake_minimum_required(VERSION 3.9.2)

into

cmake_minimum_required(VERSION 3.27)

make the symptoms go away.

Did you investigate this further? What is the smallest VERSION that
fixes your problem?

Also, why do you think this is a CMake issue and not a VTK issue?
I see the error originating in VTK's FindEXPAT.cmake in VTK, not
the one shipped in CMake.

Cheers
Timo

Bug#1050506: Could NOT find EXPAT (missing: EXPAT_LIBRARY) (found version "2.5.0")

[Mathieu Malaterre]

Source: cmake
Version: 3.27.3-1
Severity: serious
Justification: FTBFS
Tags: trixie sid ftbfs
User: lu...@debian.org
Usertags: ftbfs-20230726 ftbfs-trixie
Affects: src:gdcm

Original bug report is #1042246

Here is a minimal reproduce:

% cat ../CMakeLists.txt
cmake_minimum_required(VERSION 3.9.2)
#cmake_minimum_required(VERSION 3.27)
project(p)

find_package(EXPAT REQUIRED)
find_package(VTK REQUIRED)

The above gives:

% rm CMakeCache.txt && cmake ..
[...]

make the symptoms go away.
