Comment 13 for bug 1215411

So I've built and installed kernel 4.13.0 with this patch in 18.04.

Building mate-applets with -lcpupower fails near the end with an unusual error message:

...................

   dh_shlibdeps
dpkg-shlibdeps: error: no dependency information found for /usr/lib/libcpupower.so.4.13.0-32 (used by debian/mate-applets/usr/lib/mate-applets/mate-cpufreq-applet)
Hint: check if the library actually comes from a package.

-------------------

I've checked the contents of libcpupower1 and libcpupower-dev. Something's not right... Usually there's one real library and two symlinks to it, but here it's not so:

$ ls -l /usr/lib/libcpupower.so*
-rw-r--r-- 1 root root 79416 фев 4 21:36 /usr/lib/libcpupower.so
lrwxrwxrwx 1 root root 24 фев 4 21:36 /usr/lib/libcpupower.so.1 -> libcpupower.so.4.13.0-32
-rw-r--r-- 1 root root 22760 фев 4 21:36 /usr/lib/libcpupower.so.4.13.0-32

For reference, in Debian Stretch I have this:

$ ls -l /usr/lib/libcpupower.so*
lrwxrwxrwx 1 root root 20 янв 4 14:12 /usr/lib/libcpupower.so -> libcpupower.so.0.0.1
-rw-r--r-- 1 root root 22824 янв 4 14:12 /usr/lib/libcpupower.so.0.0.1
lrwxrwxrwx 1 root root 20 янв 4 14:12 /usr/lib/libcpupower.so.1 -> libcpupower.so.0.0.1

I don't know, is it a problem in the patch, or something's with my kernel build?
