Settings->Global Variables: add 'my_output_dir' = somewhere
Project->Properties->Build Targets->Output Filename: $(#my_output_dir)/mydll.dll
I could not get that to work.
1) In Settings->Global Variables, I added "object_dir" to Current Variable
2) then I added my folder name where my project is to "base"
3) then I set "obj" to "obj_windows" (I want the object files to go to .\obj_windows (where . is where my project is)
4) then closed and opened Project->Properties->Build targets->Objects output dir and added $(#object_dir)\Debug\
5) then re-built
But all of the objects went to ./obj/Debug
