Ah, thanks, that's a very good link! Lots to read though. Newer CMake is going to have better support for auto-detecting the library paths. Also Debian/Ubtunu is a bit at fault - it's the X86-64 ABI which actually requires /lib vs /lib64 for 32/64bit. Isn't the work-around described there for Debian a better solution though, i.e. use symlinks mapping lib => lib64? That saves users from fiddling with changing a script? Long term, we should make sure that all CMake scripts use the new method to auto-detect the lib directory correctly. | Ah, thanks, that's a very good link! Lots to read though.

Even worse, it is Linux that is breaking the rules: "This chapter describes some details that are only relevant to GNU/Linux systems and the Linux kernel.", quote from the pdf-link below. | |||
I would not use the word 'fiddling' here because it is a simple copy'n'paste sed command. Anyhow, as I am a user, too, my opinion is to preferable fiddle with build scripts, to have a 'proper' installation/file system, rather than symlinks. ;-) <BR> | |||
The situation evolved from [[Debian]] where I tried to keep things simple and that most commands work by just copy'n'paste them. Also I tried to keep the if-then-else for the reader at minimum even if the article suits for Debian-Oldstable/-Stable/-Testing on i386/amd64 and FG-Stable/-GIT. | |||
At first there was the solution with the lib64-link but, as the article history shows, in detail this was not free of the possibility for issues. Not only from this I learned that extinguishing the cause is better than creating workarounds for it. Even if 'fiddling' with scripts seems to be much more complicated at first. | |||
