error for redmax_py install

[cyxhello]

I encountered the following issues when running the command"python setup.py install":
File "setup.py", line 32, in run
self.build_extension(ext)
File "setup.py", line 57, in build_extension
subprocess.check_call(['cmake', ext.sourcedir] + cmake_args, cwd=self.build_temp, env=env)
File "anaconda3/envs/diffredmax/lib/python3.7/subprocess.py", line 363, in check_call
raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['cmake', 'DiffHand/core', '-DCMAKE_LIBRARY_OUTPUT_DIRECTORY=DiffHand/core/build/lib.linux-x86_64-cpython-37', '-DPYTHON_EXECUTABLE=/diffredmax/bin/python', '-DCMAKE_BUILD_TYPE=Release']' returned non-zero exit status 1.

How can I solve it? Thank you!!
