+Subject: [PATCH] luvi executable needs to export symbols
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Using CMake 3.12 running luvi fails with:
+
+```
+[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.
+
+Therefore, set `ENABLE_EXPORTS` to true which set `-rdynamic` explicitly.
