Hmm, did you really _read_ my post? IIRC my remark was about
installing custom/locally installed (!) software into system
directories. If I understand your mail correctly, you installed
RTAudio from a package repository, so it should stay in '/usr' and
not in '/usr/local'. 
Anyway: that doesn't seem to be the problem. Your RtAudio header
is now in /usr/local/include/rtaudio which is _not_ in the compiler's
search path! You need to run configure like this:

CPPFLAGS=-I/usr/include/rtaudio ./configure --target=linux

(after you repaired your copy/move mess :-)

No - ldconfig deals with libraries, not with header files.

 sudo ldconfig -n /usr/local/lib

ldconfig refreshes the _linker/loader_ cache, which has nothing
to do with configure.

None, it didn't do any harm-

Yes, that's anoying, to say the least.
