Hit 'send' too soon.

The build configuration way would be:

---
# dub.sdl
configuration "exe" {
  targetType "executable"
}
configuration "lib" {
  targetType "staticLibrary"
  excludedSourceFiles "src/cli/*"
}
---

Then you'd build with:

    dub build --config=lib
    dub build --config=exe

To make this version of things yield an executable depending on a library, 
you'd use something like:

---
# dub.sdl
configuration "exe" {
  targetType "executable"
  excludedSourceFiles "src/lib/*"
  importPaths "src/lib"
  libs "-L." "-L-l:libmyproject.so"
}
configuration "lib" {
  targetType "sharedLibrary"
  excludedSourceFiles "src/cli/*"
}

The one advantage of this is being able to use shared libraries. It's 
awkward.
