Linux: incorrect symbolic links to shared libraries

When building on Linux, the following shared lib files will be created:

libx265.so.1.1 (file)
libx265.so.22 (link)
libx265.so (link)

But as far as I know the number after the .so extension should only be the soversion:

libx265.so.22 (file)
libx265.so (link)

I was able to achieve this by patching source/CMakeLists.txt:

--- a/source/CMakeLists.txt
+++ b/source/CMakeLists.txt

                 LIBRARY DESTINATION ${LIB_INSTALL_DIR}
                 ARCHIVE DESTINATION ${LIB_INSTALL_DIR})

The binaries were still linked properly:
