Oh :/. I gues I'll have to replace it with an $(if ...).

Not exactly. The problem is, there's no way to choose which tools are
built, so the dependency just serves as a way to predict if the
tool will be built or not.

We're not telling anything to the build system based on those options.
IMO, patching the project file is asking for problems.

Yes, I tried without the SQL module at first, but it gave an error.
I guess it's only needed by qmlviewer, but both are built together.
