Subject: [Frei0r] Undefined symbol "pow" in hqdn3d.so

I use frei0r effects in Kdenlive (16.04.2) and apparently faced the bug
described here: https://bugs.kdenlive.org/view.php?id=2289, starting mlt
with the whole chain throws "undefined symbol error. Adding
"target_link_libraries(${TARGET} "m")" to
./src/filter/denoise/CMakeLists.txt completely fixes the problem, but since
it's fairly simple and haven't been added yet, I guess, there's a good
reason for that.

Toolchain: GCC 6.1.0 x86_64 non-multilib, glibc-2.22; Linux kernel 4.6.0.

So, I fixed it locally for me, works fine, just wanted to inform you, in
case it would help.
