"error while loading shared libraries: libcalc.so: cannot open shared object file" on Linux

[svetlyak40wt]

This happens when I'm running ./example.

And if you'll look at ldd output, you'll get the same:

% ldd example
        linux-vdso.so.1 (0x00007ffd9fbeb000)
        libcalc.so => not found
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f5c1f7a7000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f5c1f9dc000)

To solve this issue I have to run program like this:

LD_LIBRARY_PATH=`pwd` ./example

Probably this should be added to README?
