How to change Mongodb`s default storage engine(wiredtiger) to my revised wiredtiger(git source build)?

Question

I am going to modify the wiredtiger code to test the ycsb benchmark to improve performance.

Through this wiki doc (https://github.com/wiredtiger/wiredtiger/wiki/Btree-vs-LSM), I was able to test the basic wiredtiger code and the modified code at Leveldb.

Next step, I want to use YCSB to benchmark my edited wiredtiger code, but I cannot find a way to compare this.

So I setup mongodb to using YCSB benchmark since mongodb using wiredtiger as the storage engine.

But there is a problem that I don't know how I can change the mongodb`s wiredtiger storage engine(default) to I've modified(git source build).

I need advice
