aeva superbuild configure warning

Simulation Modeling Toolkit (SMTK) Software Process

Hi all, has the superbuild_add_project() macro been changed by the recent bump to common-superbuild? Or maybe the CI runners are using a different CMake with a bug? There is a new warning:

Instructing ITK to accept all compilers
CMake Warning (dev) at superbuild/cmake/SuperbuildMacros.cmake:210 (message):
  Optional dependencies for itk not found: PROCESS_ENVIRONMENT,
  ITK_ACCEPT_ALL_COMPILERS, 1
Call Stack (most recent call first):
  projects/itk.cmake:8 (superbuild_add_project)
  superbuild/cmake/SuperbuildMacros.cmake:1054 (include)
  superbuild/CMakeLists.txt:159 (superbuild_process_dependencies)
This warning is for project developers.  Use -Wno-dev to suppress it.

that has appeared recently. The relevant call is here:

superbuild_add_project(itk
  DEPENDS cxx11
  DEPENDS_OPTIONAL hdf5 vxl png zlib eigen
  ${environment}
  CMAKE_ARGS ...

where ${environment} expands to PROCESS_ENVIRONMENT ITK_ACCEPT_ALL_COMPILERS 1. So, it looks like either PROCESS_ENVIRONMENT was deprecated/removed or cmake is mistakenly lumping it in with the DEPENDS_OPTIONAL parameters.

common-superbuild did change some stuff here, but why is Windows not warning? Does reordering the arguments fix it? That is, moving it to be away from the other bit. And looking into what would be the cause if that worked…see https://gitlab.kitware.com/paraview/common-superbuild/-/merge_requests/402.
