Add version to cmake install files

[cnt0]

So for example

find_package(hyprwayland-scanner 0.3.2 REQUIRED)

will be success if 0.3.3 is installed but failure in case of 0.3.1

This installs the files with 700 on my system, for some reason. It should be 755? Am I missing anythign?

700 is weird. According to cmake documentation

Files installed by this form are by default given permissions OWNER_WRITE, OWNER_READ, GROUP_READ, and WORLD_READ if no PERMISSIONS argument is given

i.e. 644, which is exactly what I got on my system after

$ cmake -Bbuild
$ cmake --build build
$ cmake --install build --prefix install

755 for the executable, 644 for everything else.

I got 700... my fs is generally weird since a while back. When I cp executable files with sudo to /usr/bin I sometimes have to chmod them cuz they are 700 owned by root.
