OK , this may be the last post on this subject.
To implement bluez package usable for C++ development, one starts with "configure".
This script is "automatically generated"(?) and guesses many usable options / parameters to be implemented when the bluez package is actually installed - either by make and make install or checkinstall.

I took the liberty to edit it and here is a basic , no options provided output.

I do not expect the forum to analyze the enclosed, but please note highlighted.
In my view - the "configure" found the not optioned triplet, is agreeable to build shared libraries etc.
The most important part is the LAST line - that SHOULD actually build the NOT requested libbluetooth.so file of NOT specified , correctly guessed x86 architecture.

The "configure" output looks much different when both --host and --build are optioned.
End of story.
