Won't build extractor on Arch Linux

[QuetschKuh]

When installing as usual an error about "std::setprecision" comes up. After doing the fix 'make' recommends it errors at 97% because of "av_mallocz_array". I should have all dependencies installed, at least 'cmake ..' confirmed that everything was there. Although I had some trouble installing certain dependencies due to them not or barely being available on the AUR.
I also tried building on my laptop running fedora, there 'cmake ..' errors due to not finding libevent (even though it is installed using dnf).

Steps to reproduce the behaviour:

1. Install the program as described in the README
2. Wait for 'make' to reach about 70%
3. Error
4. #include <iomanip> in extractor.cpp
5. Wait for 'make' to reach 97%
6. Error

Expected behaviour:
The program builds as usual lol

Should be fixed.

tests are only to do some api tests and so shouldn't be built.
