Executables installed to non-standard location

Bug report

Hyperion installs executables to /usr/share/hyperion/bin and just symlinks them to /usr/bin

Steps to reproduce

Build the application like you normally would and like we do in the ArchLinux PKGBUILD:

$ cmake -DCMAKE_INSTALL_PREFIX="/usr/" \
     -DCMAKE_BUILD_TYPE=Release \
     -DENABLE_QT5=ON \
     -DPLATFORM=x86 \
     -DPROTOBUF_PROTOC_EXECUTABLE=/usr/bin/protoc \
     -DUSE_SYSTEM_PROTO_LIBS=ON \
     -DUSE_SYSTEM_FLATBUFFERS_LIBS=ON \
     -DUSE_SYSTEM_QMDNS_LIBS=ON \
     -DUSE_SYSTEM_MBEDTLS_LIBS=ON \
     -DENABLE_DEPLOY_DEPENDENCIES=OFF \
     ..
$ make
$ make install

See that the binaries are installed to /usr/share/hyperion/bin and that /usr/bin/ just contains symlinks to the afforementioned location.

What is expected?

The compiled binaries should be installed to /usr/bin instead of /usr/share/hyperion/bin as per the Filesystem Hierarchy Standard and the Arch Packaging Guidelines:

• /usr/share: Architecture-independent (shared) data.
• /usr/bin: Non-essential command binaries (not needed in single-user mode); for all users.

This was noticed because we have tooling in archlinux that scans through the binaries and notifies us when there are rebuilds needed (i.e. in this case for a protobuf update) where hyperion was missed because it has its binaries in this non-standard location.

We can of course patch the install step downstream, but in my opinion it would be best just to fix it here 👍🏻

What is actually happening?

Hi @christian-heusel
Just for my education… if I look at the FHS custom packages should go to /opt.
Why are you not asking having Hyperion to be installed there?

[christian-heusel]

@Lord-Grey usually only really big bundled packages (i.e. Android Studio, Zoom), which also ship their own dependency in the bundle, go to /opt/ and package-manager installed things which also link against the dependencies in /usr/lib go into /usr/bin.

I also already tried to provide some reasoning in the initial issue 😊
