There should be no difference of RHEL6 and RHEL7 for this. I suspect that on RHEL7 ADSupport is being found and that contain libzlib.so and somehow that is missing on RHEL6.

I am not sure. All his stuff works fine on rhel7. I am doing rhel6 for now. Sinisa has to build stuff manually rhel6.
He is gone for another week, and I will bug him then. Also I will soon move to rhel7 and avoid this problem.

How could this be working for Sinesa or anyone else?

I am using AD in Sinisa Viseli's DAQ distro. He compiles libz and calls it just z, in the Linux tradition.
I did a major kludge by this:
cd /usr/lib64
ln -s libz.so libzlib.so
It is nasty, but it will work for now. We just want to run some software on a uTCA crate to take some RF measurements.
We are not even using the plugins that need compression.

How have you defined HAVE_ZLIB and ZLIB_EXTERNAL in areaDetector/configure/CONFIG_SITE.local? If you define HAVE_ZLIB and ZLIB_EXTERNAL=NO it will build and use the version in ADSupport. That is what I recommend.
I think there may be a problem if you set ZLIB_EXTERNAL=YES because the library in ADSupport is called libzlib.so, but the OS version is called libz.so. We could fix that in the future, but for now just use the version in ADSupport.

I am having a link problem with AD. My exe is looking for libzlib.so
I know of libz.so, and have it installed, but I don't know what libzlib.so is. I am using Linux rhel6.
ldd of my exe
gives:
......
libz.so.1 => /lib64/libz.so.1 (0x000000343c800000)
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x0000003bc2600000)
libm.so.6 => /lib64/libm.so.6 (0x000000343b800000)
44c400000)
... ...
libxml2.so => /usr/lib64/libxml2.so (0x0000003442800000)
libzlib.so => not found
liblzma.so => /net/phoebus/ctlsdaq/CTLSDAQ/support-7.0-rhel6/opt/epics-7.0.1.1/extensions/lib/linux-x86_64/liblzma.so (0x00007f5951799000)
