I want to use LuaLaTeX since I have some quite large .tikz files, but when I do so TeXMaker does not put the output files in the 'build' directory like it would do if I use PdfLaTeX. I find the build directory very convienent to keep things organized. Anybody any idea how I can fix this?
The checkbox (Use a ‘build’ subdirectory for output files) in Texmaker adds the
–output-directory=build parameter to the PdfLaTeX command.
As you want to use the same for LuaLaTeX you could try to add
-output-directory=build manually to the LuaLaTeX command.
