CMake error in setup.py

setup.py gives me a "NumPy import failure" despite I have numpy installed and successfully imported in python 2.7.

The full error log is attached as following

Could anyone give me hint on that?

Start with setup.py and inspect cmake/FindNumPy.cmake at line 62, which is called from CMakeLists.txt line 66. Reproduce the configuration under the reported Python 2.7 environment and compare the NumPy import context used by CMake. Done means setup.py configures and builds without the NumPy import failure.
