Subject: [PATCH] Do not place CMake version in export files

Files generated by `install(EXPORT)` and `export_library_dependencies()`
may be installed with packages and consumed by dependents.  In order to
avoid re-building dependents only because the version of CMake changed,
drop the CMake version from the export file content.
