How can I specify different compile options for each source file in a project

[rjmoses]

How can I set up the projects file to have different compile options for each C/C++ source code module.

N.B.: The actual usage is radically different than this grossly simplified example. It is NOT possible to use a different name.

DEFINES += USE_MAX=3
DEFINES += USE_MAX=5

SOURCES +=
main.c \
Mod1.c \ (Would like to have DEFINES += USE_MAX=3)
Mod2.c (Would like to have DEFINES += USE_MAX=5)

Thanks

Does the answer in https://stackoverflow.com/questions/27683777/how-to-specify-compiler-flag-to-a-single-source-file-with-qmake work for you?

Thanks for the suggestion. Unfortunately, it doesn't quite fit what I need in that I would have to have separate compiler code for each module.

I am using something similar to the post you suggested for re2c tokenizer and the lemon grammar parser.

Use cmake with set_properties() and COMPILE_DEFINITIONS.
