Is it possible to include the "source" files in wixlib?

Question

Is it possible to include the "source" files in wixlib?

I have a number of C ++ solutions, each of which contains a project or projects, as well as wixlib with a fragment containing such entries as:

<File Id="MY_ID" KeyPath="yes" Source="$(var.my_path)\foo.exe" />

I would like to build "foo.exe" and enable it in wixlib, and then create a WiX project that binds several of these wixlibs and creates an MSI.

The reading I did seems to suggest that WiX3 and its support support this, and it is preferable to use merge modules.

I am currently using an environment variable that describes the path to the binary files that is used during the link to search for light.exe files. However, it has the following disadvantages:

• version of files for changing wixlib compilation time and wixlib binding in MSI and
• Being specific to the environment used to build wixlib (for example: if the wixlib compilation and communication were performed on different computers, both of them should have the necessary binary files).

I do not have much experience with wixlib itself, but is this a -bfswitch lit.exefor? From the help help lit.exe:

   -bf      bind files into the library file
