Description Dennis Schridde 2012-09-07 11:09:01 UTC 
In a CMakeLists.txt, find_package(Lua51) is supposed to find an instance of Lua 5.1. On Gentoo it also finds Lua 5.2, because the package is not slotted.

$ eix -ce lua

$ q file -v /usr/lib64/liblua.so
dev-lang/lua-5.2.1 (/usr/lib64/liblua.so)

Please report this upstream and link here back. We (gentoo) don't modify the shipped module.

The idea was more to get Lua into a shape were FindLua51.cmake would actually bring up something different than FindLua50.cmake. I might be using "legacy" applications/code, which uses an older version of Lua, and have no influence on it being updated (except with custom patches, diverging me from my upstream).

@Rolf as i know you are very active in cmake upstream, how about to pick up this issue?
Comment 5 Johannes Huber (RETIRED) gentoo-dev 2015-01-16 21:16:55 UTC 
Could someone please attached patch in upstream bug and report back here?
