Fix cmake_minimum_required to be 2.8.12

ejoerns · wilx · commit f3e4218aa997 · 2017-02-28T09:47:46.000+01:00
The src/CMakeLists.txt makes use of the `INCLUDES DESTINATION` install
argument which was introduced into CMake with rev '650e61f'.
The first CMake release including this rev is 2.8.12.

Thus the minimum required CMake version must be adjusted to 2.8.12.
