Meshroom 2025.1.0 has a bug (alicevision/Meshroom#2808) where paths containing spaces are not properly quoted when
meshroom_computeis launched internally. This causesmeshroom_batchto fail with unrecognized arguments when the pipeline .mg file lives in a directory with spaces (e.g., OpenLIFU installation dir).Work around this by copying the pipeline file to the temp directory before passing it to meshroom_batch.
However, this is not a full guarantee if the temp directory itself contains spaces (i.e. if the username has spaces) - although this is usually not the case.
