Changeset 7944 for code/branches/kicklib/cmake/tools/FindLua5.1.cmake

Timestamp:

Message:

Renamed Lua library to "Lua5.1" because that's also what the official Linux repositories call it to differentiate it from Lua v5.0.
Also simplified the CMake find script a lot since it doesn't have to find both Lua versions anymore.

  #    Reto Grieder
  #  Description:
- #    Finds either Lua 5.0 or Lua 5.1 on the system. The script regards the
- #    VERSION, EXACT, REQUIRED and QUIET arguments. A note about the EXACT
- #    argument: EXACT 5 will match all Lua 5 versions.
+ #    Finds Lua 5.1 on the system.
+ #    Handles REQUIRED and QUIET arguments.
  #    When the search was successful, the following variables are set:
- #    LUA_INCLUDE_DIR, LUA_LIBRARIES, LUA_VERSION, LUA_FOUND
+ #    LUA5.1_INCLUDE_DIR, LUA5.1_LIBRARY, LUA5.1_VERSION, LUA5.1_FOUND
