No.  An invocation of cppumaker only generates the header files 
corresponding to those UNO types you tell it to.  So your makefile's 
invocation of cppumaker will presumably only generate header files 
corresponding to your newly introduced .idl files.

So this part is about the UNO types that ship with the SDK.

Where the header files are generated to is specified in the call to 
cppumaker.  The header file for the standard UNO types generated via 
that rule in the SDK's settings/stdtarget.mk are generated to $(OUT_INC) 
as defined in settings/std.mk.

By design, the SDK never points into a LO build's workdir or solver.  It 
only points at parts of a LO installation.

But, to get your own local makefile experiments started, it can be 
easier to "cheat" and re-use the header files generated for the standard 
UNO types there, in solver/*/inc/udkapi and solver/*/inc/offapi (so you 
would need to add two -I flags).
