Can you help me understanding a build error?

Hi, I'm just trying to build wireshark on a Windows 10 x64 environment from source code available on the website. I do not modify the source code until now.

Folllowing the developer's guide, i'm generating the build file at paragraph 2.2.11.

the cmake command line return the following error :

-- Found SBC: C:/Nicolas/Dev/wireshark-win64-libs/sbc-1.3-win64ws/include
-- SBC FOUND
-- SBC includes: C:/Nicolas/Dev/wireshark-win64-libs/sbc-1.3-win64ws/include

What can generate this error ? What are SETCAP and SH and what do i need to do to correct this error ?

Thank you for your help!
