Build davisking.dlib failed, not exist zlib.h and mex.h

[z-pc]

Describe the bug
I add "org.sw.demo.davisking.dlib", the compiler (VS2019 16.10.1) not found "zlib.h " and "mex.h"
This's some last error lines:

I tried again by "Actions" from website, same error.
Some main lines in CMakeFile:

find_package(SW REQUIRED)

	org.sw.demo.artifexsoftware.mupdf
	org.sw.demo.davisking.dlib
	)
sw_execute()

add_executable(example_classifier
	example/example_classifier.cpp)

target_link_libraries(example_classifier
	PUBLIC org.sw.demo.davisking.dlib)

Did I miss something?
Thanks.

Hi,

dlib was not packaged properly.
It is huge.
I added it only as a stub.

[egorpugin]

If you want to use it within sw, I need help in packaging.

Instruction:

1. Create sw.cpp with contents from https://software-network.org/org.sw.demo.davisking.dlib/specification
2. Update dlib version there to get the latest release (19.22).
3. Run sw build --fetch in the directory with sw.cpp.
4. Fix raised issues in build script (sw.cpp).
