building on debian 8

1. issue: LIBTAG

checking for TAGLIB… no

# LC_ALL=C aptitude search tag | grep dev | grep ^i
i libid3tag0-dev – ID3 tag reading library from the MAD proje
i libtag1-dev – audio meta-data library – development file
i libtaglib-cil-dev – CLI library for accessing audio and video

libtag1-dev is about v1.9 and should cover it. What could be wrong?

2. pvr-hts.
Ran with https://github.com/kodi-pvr/pvr.hts/tree/Krypton , adding -b Krption to git.

step 4 fails: wants cmake 3.1 but deb8 has 3.0.2.
Not sure how to tackle this. compile cmake manually? backports?
