For this question I'll be using a specific example, but really this generalizes to pretty much any binary on linux that can't seem to find its' dependent libraries. So, I have a program that won't run because of missing libraries:

./cart5: error while loading shared libraries: libcorona-1.0.2.so: cannot open shared object file: No such file or directory

ldd sheds some light on the issue:

linux-vdso.so.1 =>  (0x00007fff18b01000)
libcorona-1.0.2.so => not found
libstdc++.so.6 => /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.3/libstdc++.so.6 (0x00007f0975830000)
libm.so.6 => /lib/libm.so.6 (0x00007f09755af000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007f0975399000)
libc.so.6 => /lib/libc.so.6 (0x00007f0975040000)
libz.so.1 => /lib/libz.so.1 (0x00007f0974e2b000)
/lib64/ld-linux-x86-64.so.2 (0x00007f0975b36000)

However, corona is installed:

oliver@human$ find / -name libcorona-1.0.2.so 2> /dev/null

/usr/local/lib64/libcorona-1.0.2.so
/home/oliver/installed/corona-1.0.2/src/.libs/libcorona-1.0.2.so

How do I tell the binary where to look for the "missing" library?
