'sip.h' file not found

[Atomzdq]

My sip version is 4.19.14 . When I cmake the Arcus, the step of make -j4. error happened:
fatal error:
'sip.h' file not found
#include <sip.h>
1 error generated.

How I solve it? Should I install python3-sip-dev? But I don't know how to install it, Please help me. How to install python3-sip-dev and python-dev on mac osx?

In CMake, what does your variable SIP_INCLUDE_DIR say? Is there a sip.h file in there somewhere?
