Description

As mentioned in a comment under #14814, omc tries to copy some files from the /opt/openmodelica-nightly directory, but fails because they are owned by root with permission number 700, thus not accessible by normal users:

cp -a \"/opt/openmodelica-nightly/bin/../share/omc/runtime/c/fmi/buildproject/\"* 332.fmutmp/sources
cp: cannot open '/opt/openmodelica-nightly/bin/../share/omc/runtime/c/fmi/buildproject/config.guess' for reading: Permission denied
cp: cannot open '/opt/openmodelica-nightly/bin/../share/omc/runtime/c/fmi/buildproject/config.sub' for reading: Permission denied

This occurs on my machine running Fedora 43, but not inside a container based on Debian 13.

Steps to Reproduce

• Install OpenModelica Nightly as instructed in the Download Linux page, on section "RPM packages", on Fedora 43;
• Download minimal-nonworking-example-fedora.tar.gz, extract it and run omc buildfmi.mos.

Version and OS

• OpenModelica Version: OpenModelica 1.27.0~dev-8-gf6de017
• OS: Fedora 43
