Changes for aarch64
Hi @kolos, can you merge these changes for the aarch64 architecture ?
It defines a new config/ file for aarch64-centos7, and makes two minor adjustments in the CMakeLists.txt file"
Use of ZLIB for ziop (which implies using FindZLIB.cmake) is required in cross-compilation mode, or we pick up the zlib version from the host.
The omnicpp executable should have no dependencies on omniidlmodule or python, it's just a C preprocessor (?)
cheers, Reiner
