Hi Werner: Lua5.1 is available with my brand new Debian squeeze (testing) system, but it didn't work for a PLplot build because I did not set a special cmake option. That lead me to look at the logic in cmake/modules/lua.cmake, and I have greatly simplified a few stanzas there (revision 11087) which I believe were seriously twisted by no-longer-relevant 2.4.x concerns. I have checked the relevant FindLua CMake modules for 2.6.0 and 2.8.2, and they consistently only define LUA50_FOUND for the 5.0 version and LUA51_FOUND for the 5.1 version so I have relied on those variables exclusively for my logic simplification.
The result is Lua5.1 users no longer have to set a special option (in fact all user choice of Lua version is gone). Instead, our build system simply uses Lua-5.1 if that is available, and otherwise Lua-5.0 if that is available and checks for consistency between the lua command version and the Lua libraries. Please review these changes. I have tested the new logic on a Lua-5.1 system for CMake-2.8.2. The new logic appears to work perfectly for that case and is so simple I believe it will work fine on Lua-5.0 or Lua-5.1 systems for CMake-2.6.0 and all higher versions of CMake.
