BASEMENT v4.2.0 GUI on Linux fails with "no model definition found"

Hello,

I'm running BASEMENT v4.2.0 on Ubuntu 22.04 (GUI)

Setup:
- OS: Linux (Ubuntu), locale en_US.UTF-8 / LC_NUMERIC=ja_JP.UTF-8
- BASEMENT v4.2.0, installed binaries in /usr/bin/BMv4_*
- Test case: TestCases/1_H_CDB_Benchmark/BMv4/10k (circular dam-break benchmark)
- The same test case (same files) runs successfully on Windows with the GUI.

Steps to reproduce on Linux:
1. Open the test case folder in the BASEMENT GUI.
2. GUI correctly displays the contents of model.json.
3. Click "Write".

Result in GUI:
STDOUT : BASEMENT v4.2.0 (v4.2.0)
STDOUT : BASEHPC setup binary
STDERR : -> no model definition found
STDERR : -> ... unfortunately BASEMENT is killed!

However, running the setup binary directly from the command line in the same folder works perfectly when the model file is passed with the -f flag:

/usr/bin/BMv4_BASEHPC_setup -f model.json -o setup_test.h5

-> completes successfully, "BASEMENT successfully processed all necessary jobs!"

But running it WITHOUT -f (i.e. model.json as a positional argument) fails immediately with:

PARSE ERROR: Argument: model.json
             Couldn't find match for argument

Could you please check how the Linux build of the GUI constructs the command line for BASEHPC_setup?
It looks like a Linux-specific packaging/argument-passing bug rather than a model.json compatibility issue.

Happy to provide more logs or test further if useful.

Thanks,
Maxim
