I use the following code to install the depences of the dynamic libraries, but libgfortran remains unresolved although it seems to be well detected by the system.

That is…interesting. Is `libgfortran.so.5` an actual ELF binary or is it a linker script? `file` should be able to tell the difference, but if not, peeking at it with `less` should help.

Hrm. That is quite strange. I don’t know if there are any verbose logs available from `file(GRD)` or not. All I can recommend is either to provide a Docker image which reproduces the issue so that we can debug or to trace the execution of CMake to determine why it misses this library.
