MDIS installation in Red Hat 9 is unusable with default paths

[mad-jsanjuan]

When installing MDIS in Red Hat versio 9, the installed binaries and libraries are not being tracked by the system. The PATH environment variable and ldconfig will not let the user use the installed tools.

From the MDIS makefiles we get:

# The directory in which the user state programs are to be
# installed. Often something like /usr/local/bin. (relative to
# the target's root tree)

BIN_INSTALL_DIR = /usr/local/bin

# The directory in which the shared (.so) user mode libraries
# are to be installed. Often something like /usr/local/lib.
# (relative to the target's root tree)

LIB_INSTALL_DIR = /usr/local/lib

# The directory in which the static user mode libraries are to
# be installed. Often something like /usr/local/lib on
# development host. For cross compilation select a path
# relative to your cross compilers lib directory.

STATIC_LIB_INSTALL_DIR = /usr/local/lib

We need to configure/document how to setup PATH and ldconfig stuff for Red Hat distros.

This is only an issue when using the scan_system.sh script. The MDIS wizzard does let you choose these options, but this should probably also be supported on the scan_system.sh script.

Yes, or that the user has to change the *_INSTALL_DIR within MDISWIZ. Both should be described in QUICKSTART.md.

For the scan_system.sh, we could detect the running distro and change the paths automatically at runtime. What do you think?

Ok, now I see in your pull request https://github.com/MEN-Mikro-Elektronik/13MD05-90/pull/274 that you already had the same idea. 👍

In QUICKSTART.md is noted where the MDIS executables are located (see Binary Locations). Please adapt it accordingly. And I have to note this in the UM as well.

Closing the issue as it is already merged with all changes suggested by @dpfeuffer.
