building source3 subsystems and libs

[moore chestnut]

  hello,

is there any way to individually build subsystems and libraries?

for example:

the msrpc3 library in  source3/wscript_build
bld.SAMBA3_LIBRARY('msrpc3',

or
bld.SAMBA3_SUBSYSTEM('samba3util',

when I try waf or waf msrpc3 in the source3 dir, it does not work.

currently trying on a 4.11.0 source tree.

I have read through the https://wiki.samba.org/index.php/Waf
and tried the samples with no success.

Does this work for source3 libs/subsystems?

Thank you for any guidance.
