This is more tolerant that the simple check based on version numbers.
Different versions can be compatible if they have the same SHA-1 when
considering only those files that can influence xswiftbus.
The config is loaded from json files by qmake, and we define the qmake
function `swiftConfig` for checking whether a feature is enabled.
This function can be directly used in `buildconfig_gen.cpp.in`,
so the trick with C++ comment tokens in variables is not needed.
Summary:
Configuration tests check whether all mandatory dependencies to build
swift are met. They can also be used to check optional dependencies, which
results in certain features to be enabled or disabled.
This first batch tests for mandatory libraries libpng, zlib and OpenGL.
If this is not tested and some libraries are missing, the developer will
be notified very late in the build.
