How to build a project with an icon by `cabal build` or `stack build`

Question

I want to build an executable with an icon. By googling it, I find the instruction here, but it only works by compiling a source file with ghc.

If I want to build a project with an executable by cabal build or stack build, how should I configure the .cabal or .yaml files such that cabal build or stack build can directly create an executable with an icon?

I've googled it for a while, but nothing useful.

I appreciate it if any tips are given.

What if you include `"$targets": Icon.o` in the `ghc-options:`? — Willem Van Onsem, Oct 22 '19 at 12:22
Thanks! That works although there is a warning telling "the following files would be used as linker inputs, but linking is not being done: Icon.o" — Z-Y.L, Oct 22 '19 at 12:49

According to @Willem Van Onsem's suggestion, the following is the solution:

for a stack project, add the following configure into the stack.yaml file

    ghc-options:

        "$targets": Icon.o

for a cabal project, add the following ghc-options into the .cabal file

    ghc-options:

        Icon.o

I have problem creating the Icon.o file. Winres give me syntax error. My post : https://stackoverflow.com/questions/65095586/syntax-error-when-running-winres-trying-to-set-executable-icon – Johannes Green Dec 01 '20 at 18:35
