To put a target file in a directory different from its dependent file
in a makefile, you must explicitly name the path for the target file.
When compiling, use the /Fo switch and a path to place the .OBJ file
in a different directory from the source. When linking, give the full
pathname when specifying the .EXE file parameter.
The following example demonstrates both aspects:
# MAKE SURE THERE IS A TRAILING BLANK AFTER THE FINAL BACKSLASH
LONGPATH=e:\c51\binr\
SHORTPATH=e:\c51\
pixel.obj: $(LONGPATH)pixel.c
# USE /Fo SWITCH TO PUT .OBJ FILE IN DIFFERENT DIRECTORY
cl /Fo$(SHORTPATH) /c $(LONGPATH)pixel.c
Note that if you use a macro in the makefile for the pathname (as
shown above), then you must be sure the final backslash (\) in the
pathname is followed by a trailing space. If there is no trailing
space, the backslash will be interpreted as a line-continuation
character. When you create the makefile, use an editor that will
preserve a trailing space, such as the Programmer's WorkBench or the
Microsoft Editor (if you set the "trailspace" switch).
