You didn't say what exactly you downloaded and are trying to install. 
You can download either package with pre-compiled libraries (for some 
platforms), or a source distribution package and compile it yourself. In 
either case, and according to 
http://www.boost.org/doc/libs/1_61_0/more/getting_started/unix-variants.html#easy-build-and-install, 
you'd need to run ./bootstrap.sh with --prefix option, and ./b2 install 
without it. I never install prebuild libraries so I have no experience 
with such packages.

I'd recommend a careful reading of the above, and the associated 
documents that are available at the Boost site. Occasionally I have to 
compile and install Boost myself (usually because the system supplied 
package is too old), but so far I found this process rather fluent and 
well documented. It really is worth reading through the docs.

As for the latter part, your question it's a bit vague. When you compile 
and link your sources that make a use of Boost libraries, it's a matter 
of compiler and linker directives that tell compiler where to search for 
header files and tell linker where to look for libraries. When you want 
to run your programs that use Boost shared libraries, then the system 
loader has to find these libraries. But all this stuff is platform 
specific, sensitive to the linker options you have used and other 
variables. By default gcc on Ubuntu will probaly look into /usr/include 
and /usr/local/include for headers, and /lib, /usr/lib and 
/usr/local/lib for libraries. But you can use -I and -L to specify 
custom locations.

Cheers,

Leon
