Source: cmake
Version: 3.27.3-1
Severity: serious
Justification: FTBFS
Tags: trixie sid ftbfs
User: [email protected]
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 ..
[...]
CMake Error at
/usr/share/cmake-3.27/Modules/FindPackageHandleStandardArgs.cmake:230
(message):
Could NOT find EXPAT (missing: EXPAT_LIBRARY) (found version "2.5.0")
Call Stack (most recent call first):

CMakeLists.txt:6 (find_package)
It is unclear why changing:
cmake_minimum_required(VERSION 3.9.2)
into
cmake_minimum_required(VERSION 3.27)
make the symptoms go away.
Thanks for comments,

Closes: 1050506
Changes:
vtk9 (9.5.2+dfsg3-5) unstable; urgency=medium
.
* Team upload.
* debian patch findEXPAT_version_fix_MR12826.patch applies upstream
MR#12826 to fix expat version handling. Closes: #1050506
* 9.5.2+dfsg3-3 disabled viskores on 32-bit arches, since
ParaView::RemotingViews optionally uses VTK::vtkviskores
but (ThirdParty) viskores exhausts virtual memory on 32-bit arches
* disable viskores on alpha, which is 64-bit but also exceeds
available memory
