Add yaml-cpp libraries to examples

Try to solve yaml-cpp linking errors by adding yaml-cpp libraries
explicitly to the examples.
Add wait in the test to prevent the assertion
Fix Mass/Stiffness matrix transformation on FemElement1D

The transformation of the local matrix to the global matrix was done backward.
m_R0 is the rotation that transform local coordinates into global coordinates. So the matrix transformation should be:
MGlobal = R0.MLocal.R0^T
