FindLua50

Note

This module is specifically for Lua version branch 5.0, which is obsolete and not maintained anymore. In new code use the latest supported Lua version and the version-agnostic module FindLua instead.

Finds the Lua library. Lua is a embeddable scripting language.

When working with Lua, its library headers are intended to be included in project source code as:

#include <lua.h>

and not:

#include <lua/lua.h>

This is because, the location of Lua headers may differ across platforms and may exist in locations other than lua/.

Result Variables

This module defines the following variables:

Lua50_FOUND

Boolean indicating whether Lua is found. For backward compatibility, the LUA50_FOUND variable is also set to the same value.

Cache Variables

The following cache variables may also be set:

LUA_INCLUDE_DIR

The directory containing the Lua header files, such as lua.h, lualib.h, and lauxlib.h, needed to use Lua.

LUA_LIBRARIES

Libraries needed to link against to use Lua. This list includes both lua and lualib libraries.

Examples

Finding the Lua 5.0 library and creating an interface imported target that encapsulates its usage requirements for linking to a project target:

find_package(Lua50)

if(Lua50_FOUND AND NOT TARGET Lua50::Lua50)
  add_library(Lua50::Lua50 INTERFACE IMPORTED)
  set_target_properties(
    Lua50::Lua50
    PROPERTIES
      INTERFACE_INCLUDE_DIRECTORIES "${LUA_INCLUDE_DIR}"
      INTERFACE_LINK_LIBRARIES "${LUA_LIBRARIES}"
  )
endif()

target_link_libraries(project_target PRIVATE Lua50::Lua50)
