The complexity of building Qt Creator plugins

Building Qt Creator plugins can be very complex for regular users.
The plugins all rely on the Qt Creator source code, and more specific, some of the headers and .pri files.

Usually, or almost always, these files are not installed by the package management system of a distribution. This renders the usage of the plugin template of Qt Creator and building any plugin impossible.

My advice therefor is to download the Qt Creator source code and build it yourself. Then it is pretty easy to build any plugin.

Now, building plugins should not be needed by most users. I need to find a way to create binary packages for the most used systems. In that respect, I'm looking at virtualbox.
I'm going to turn a computer I have into a system that hosts the most common systems and their compilers and use that as a basis to create system specific packages. I'm not sure if I should use gentoo as the host OS or Windows. My preference is gentoo.

I also need a new graphicscard for this PC. Estimated time of purchase is somewhere mid january, after the holliday spendings. Untill then, I'll only the source code will be available.

Untill the plugin is also ready for a 1.0 release, there will be no versioned source code.
