checking json project: different results for different starting directories

[vilox]

json project indicates directory: and file: for each compilation unit, so I we should be able to run

$ cppcheck --project=/path/to/bar.json

and do not care of what directory is current for cppcheck now.
However the results of checking may differ for different starting working directory.
Let wrap into json project the command line

$ cppcheck -DANY -I /tmp/R/include -I /tmp/R/bar/part_1 /tmp/R/bar/part_2/bar.c

from [preprocessor includes wrong header files] topic of this forum.

$ cat bar.json

[
    {
        "arguments": [
            "gcc",
            "-DANY",
            "-I/tmp/R/include",
            "-I/tmp/R/bar/part_1"
        ],
        "directory": "/tmp/R/bar",
        "file": "part_2/bar.c"
    }
]

Then

$ cd /
host:/$ cppcheck --project=/tmp/R/chkr/bar.json
Checking /tmp/R/bar/part_2/bar.c ...
/tmp/R/include/foo.h:7:0: error: #error Foo was not configured [preprocessorErrorDirective]
# error Foo was not configured
^

but

host:/$ cd /tmp/R/bar
host:bar$ cppcheck --project=/tmp/R/chkr/bar.json
Checking part_2/bar.c ...
Checking part_2/bar.c: ANY=1...
host:bar$
