When compiling the C-API with OpenBLAS, not mkl, the OpenBLAS library failed to install. The error occurs during the peroid of make install:

Then there will be a link error when using the paddle C-API library.

And I must copy the OpenBlas library to the installation package of the paddle by myself.
