If you build Lua from source as a shared library, be sure to include the
-fPIC option to build position-independent code that can be linked to
Wireshark. See for example this patch and the build script:
https://git.archlinux.org/svntogit/packages.git/tree/trunk/liblua.so.patch?h=packages/lua52
https://git.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/lua52

However if you are using Fedora, install the compat-lua and
compat-lua-devel scripts. See also tools/rpm-setup.sh or
packaging/rpm/wireshark.spec.in files.
