How to statically link all libraries except a few using g++?

I have a requirement that I link all my libraries statically including libstdc++, libc, pthread etc. There is one omniorb library which I want to link dynamically.

Currently I have dynamically linked all the libraries. ldd shows the following

linux-vdso.so.1 =>  (0x00007fff251ff000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f291cc47000)
libomniDynamic4.so.1 (0x00007f291c842000)
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007f291c536000)
libm.so.6 => /lib64/libm.so.6 (0x00007f291c2e0000)
libgomp.so.1 => /usr/lib64/libgomp.so.1 (0x00007f291c0d7000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f291bebf000)
libc.so.6 => /lib64/libc.so.6 (0x00007f291bb66000)
/lib64/ld-linux-x86-64.so.2 (0x00007f291ce63000)
librt.so.1 => /lib64/librt.so.1 (0x00007f291b95d000)
libomniORB4.so.1 (0x00007f291b6aa000)
libomnithread.so.3 (0x00007f291cf35000

I need ldd to show libomniDynamic4.so.1 as the only dynamically linked library.

How do I achieve this?
