Support Clang/LLVM build on FBSD

[marian-cingel]

• Update CMakeList to support installation to PREFIX directory

• Inotify does not exists on FBSD - disable WatchPaths for now

• FreeBSD does not support anonymous socket, so explicit 'LAMINAR_BIND_RPC=IP:port' is required

• /proc, required by Laminar, is usually not mounted on FBSD, so: 'mount -t procfs proc /proc'

  or add into /etc/fstab: 'proc /proc procfs rw 0 0'

• ld.lld requires explicit emulation for binary blobs, add a new variable LINKER_EMULATION_FLAGS for this purpose

Hi, thanks for this! In case you weren't aware, there was an earlier attempt to port to FreeBSD that stalled: #170

Hello, no problem, thanks for creating the Laminar in a first place. Yes, I saw the #170. Fortunately I don't have any issues with autoptr, using Clang/LLVM_17 on FreeBSD14. Maybe in week or two I will add a FBSD support for PathWatcher, so please wait with this MR. FYI: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=273827

Looks good so far. Waiting in case PathWatcher comes along.

Done. It requires to just add libinotify library in CMakeLists.txt - a bridge between inotify API and FBSD kqueue. Do you want to keep "#ifndef WATCH_PATHS_UNSUPPORTED" in server.cpp ? In case someone wants to run it on more exotic systems or should I remove it completely ?

I'd prefer you remove it, it will be easy to reintroduce if we ever need it
