[Lldb-commits] [lldb] [lldb][test] skip Lua tests when the Lua interpreter is not found (PR #164793)

[Vincent Palatin via lldb-commits]

https://github.com/vpalatin created https://github.com/llvm/llvm-project/pull/164793

When Swig is installed but not any Lua interpreter, the cmake script in `lldb/cmake/modules/FindLuaAndSwig.cmake` will execute `find_program(LUA_EXECUTABLE, ...)` and this will set the `LUA_EXECUTABLE` variable to `LUA_EXECUTABLE-NOTFOUND`.

Ensure that in this case we are skipping the Lua tests requiring the interpreter.

Subject: [PATCH] [lldb][test] skip Lua tests when the Lua interpreter is not
 found

When Swig is installed but not any Lua interpreter, the cmake script in
`lldb/cmake/modules/FindLuaAndSwig.cmake` will execute
`find_program(LUA_EXECUTABLE, ...)` and this will set the `LUA_EXECUTABLE`
variable to `LUA_EXECUTABLE-NOTFOUND`.

Ensure that in this case we are skipping the Lua tests requiring the
interpreter.
