Can you add support with xevan algorithm?

[vanthoi]

I see there is a fork of ccminer supporting xevan here:
https://github.com/krnlx/ccminer-xevan

So you can integrate it into your source code always.
Since every time I want to use xevan I have to move between the libraries a bit inconvenient.

And I have an error on Cent OS with ccminer version 2.2.5 as follows
./ccminer: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21 'not found (required by ./ccminer)

No errors were generated at build.sh.
I have to execute the following command before running ccminer:
export LD_LIBRARY_PATH = / usr / local / lib: / usr / lib: / usr / local / lib64: / usr / lib64

I am using CUDA 8.0 because ccminer version 9.0 reporting is not supported
Although I build successful

Thank!
