Good idea, trying in https://github.com/BLAST-WarpX/warpx/pull/6448 Branch: https://github.com/ax3l/amrex/tree/fix-linop-mlmg

That changes the error somewhat, now: ``` ... 2025-12-09T19:24:28.8177040Z 10>D:\a\warpx\warpx\build\_deps\fetchedamrex-src\Src\LinearSolvers\MLMG\AMReX_MLCellLinOp.H(533,14): error C2039: 'define': is not a member of 'std::array' [D:\a\warpx\warpx\build\lib_3d.vcxproj] 2025-12-09T19:24:28.8178335Z (compiling source file '../Source/Initialization/DivCleaner/ProjectionDivCleaner.cpp') 2025-12-09T19:24:28.8179762Z C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\MSVC\14.44.35207\include\array(402,7):...

@c-wetterer-nelson can you potentially update the SENSEI image we use in AMReX/WarpX to include CMake 3.24 or newer? :pray:
