Issue: Improvement over compiled shared object.

[hwyao]

Description

When we want to integrate the LCQPow solver to some other packages e.g the ROS packages, we expect that we can use the static or shared object from this solver. However when we try to do so, we could meet multiple problems.

Expected: We use one LCQPow shared object and include its header files in our own CMakeLists.txt and everything finished. Actual: The linking is difficult, we have to link 3 objects in a correct way, otherwise we will meet many problems.
