If I understand correctly, this is exactly what's *not* guaranteed:

"Rules specified by calls to this command within a source directory are
executed in order during installation. The order across directories is
not defined." (documentation of INSTALL() command)

Perhaps, the CMake manual could be clarified in this regard since the
INSTALL() commands' order of execution is sometimes quite important.
