luvi fails to run when it was build with CMake 3.12+:
```
[string "return require('init')(...)"]:1: module 'init' not found:
no field package.preload['init']
no file './init.lua'
no file '/usr/share/luajit-2.0.5/init.lua'
no file '/usr/local/share/lua/5.1/init.lua'
no file '/usr/local/share/lua/5.1/init/init.lua'
no file '/usr/share/lua/5.1/init.lua'
no file '/usr/share/lua/5.1/init/init.lua'
no file './init.so'
no file '/usr/local/lib/lua/5.1/init.so'
no file '/usr/lib/lua/5.1/init.so'
no file '/usr/local/lib/lua/5.1/loadall.so'
```
Looking at link.txt for the luvi executable shows that `-rdynamic` is
not set anymore in CMake 3.12. This has the effect, that symbols are
missing in the `.dynsym` section in the binary.
The patch, sets `ENABLE_EXPORTS` to true in CMakeLists.txt to force setting
`-rdynamic` explicitly.

Using CMake 3.12 running luvi fails with:
|
|
|
|
```

Therefore, set `ENABLE_EXPORTS` to true which set `-rdynamic` explicitly.
