When creating deb package for your project you need to specify at DEBIAN/control file at Depends: field to what packages your project depends. To do that you can invoke follwing command on all binaries and libraries that you want to put into your package. This will help you fill in Depends: field.
Before start you should install apt-file: # apt-get install apt-file
ldd $LIBRARY_PATH | awk '/=>/{print $1}' | \
while read n; do echo "=== $n maybe found at: ===" && apt-file search $n | \
awk '{print $1}' | sed 's/://' | sort; done | uniq
Example:
$ ldd /usr/lib/libmodplug.so.1 | awk '/=>/{print $1}' | \
while read n; do echo "=== $n ===" && apt-file search $n | \
awk '{print $1}' | sed 's/://' | sort; done | uniq
$ ldd /usr/lib/libmodplug.so.1 | awk '/=>/{print $1}' | while read n; do echo "=== $n ===" && apt-file search $n | awk '{print $1}' | sed 's/://' | sort; done | uniq

So when you building deb package for your project, probably dependencies that you will put to your DEBIAN/control file are
Depends: libstdc++6, libc6, libgcc1
