It seems that the above two variables play no role in the version string for
the link file names.
Rather the usage of "set_target_properties(libname PROPERTIES VERSION
${ORX_VERSION})" for each
"libname" defines the version string to use [1]. So probably using
"${ORX_MAJOR}" instead of
"${ORX_VERSION}" would make the version string in the link names to consist of
"5" only.

[1] Search for "VERSION" in:

to yield:
"... For shared libraries VERSION and SOVERSION can be used to specify the
build version and API
version respectively. When building or installing appropriate symlinks are
created if the
platform supports symlinks and the linker supports so-names. If only one of
both is specified
the missing is assumed to have the same version number. For executables
VERSION can be used to
specify the build version. When building or installing appropriate symlinks
are created if the
platform supports symlinks. For shared libraries and executables on Windows
the VERSION
attribute is parsed to extract a “major.minor” version number. These
numbers are used as the
image version of the binary. ...".
