[CMake] CMAKE_INSTALL_PREFIX problem

[Petr Kmoch]

I don't know why @ was inserted, but here's why it overrides the absolute
path: because it has no special meaning. The path then becomes "@/sbin",
which is not an absolute path (doesn't start with '/'), so the install
prefix is prepended normally. Bear in mind that Unix directory and file
names can contain any characters except '/' and NUL.

About variable substitution:

${var} is the normal way to expand variables.

@var@ is primarily intended for use with configure_file(). I believe it
works during normal CMake runs as well, but don't use it like that, it will
only add confusion.
