[3dprinter-general] Bug#1032930: pynest2d: FTBFS with cmake 3.25: Libnest2D could not be found because dependency clipper could not be found.

[Andreas Beckmann]

Source: pynest2d
Version: 5.0.0-1
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)

Hi,

pynest2d/experimental started to FTBFS after some (transitive)
build-dependency has been upgraded. Most likely this is caused by cmake
3.25 (the last successful build was done with cmake 3.23).
This does not affect the version in sid since that does not seem to
check for clipper.

CMake Warning (dev) at /usr/share/cmake-3.25/Modules/FindPackageHandleStandardArgs.cmake:438 (message):
  The package name passed to `find_package_handle_standard_args` (Clipper)
  does not match the name of the calling package (clipper).  This can lead to
  problems in calling code that expects `find_package` result variables
  (e.g., `_FOUND`) to follow a certain pattern.
Call Stack (most recent call first):
  /usr/lib/cmake/Libnest2D/Findclipper.cmake:67 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)

This warning is for project developers.  Use -Wno-dev to suppress it.

-- Found Clipper: /usr/include/polyclipping
CMake Error at CMakeLists.txt:33 (find_package):
  Found package configuration file:

    /usr/lib/cmake/Libnest2D/Libnest2DConfig.cmake

  but it set Libnest2D_FOUND to FALSE so package "Libnest2D" is considered to
  be NOT FOUND.  Reason given by package:

  Libnest2D could not be found because dependency clipper could not be found.
