Some libraries uses the non-conventional SONAME scheme like
`libssl.so.1.1` or `libboost_system.so.1.64.0`, but CMake didn't count on
such versioned libraries. This commit modify regular expressions to match
relaxed format of shared library name for determining various linker options,
especially `RPATH`.
Note that support for one component has been available since v2.8.12.

Fixes: #15938
