The issue is the MAIN_DEPENDENCY, which does not behave as you expect.
The documentation [1] says:
MAIN_DEPENDENCY
Specify the primary input source file to the command.
[...]
Each source file may have at most one command specifying it as its
main dependency. A compile command (i.e. for a library or an
executable) counts as an implicit main dependency which gets
silently overwritten by a custom command specification.
The reason for this design is the Visual Studio
Code Generator, which attaches rules to sources instead of outputs.
The correct solution in your case is to put everything under DEPENDS
and not use MAIN_DEPENDENCY at all.
Cheers
