Preset generator cannot handle "const auto FOO = 42u;"

[frankier]

If we have a source file with something like:

namespace bar {
const auto FOO = 42u;
}

We get:

Caused by: org.bytedeco.javacpp.tools.ParserException: /path/to/header.hpp:2:Could not parse declaration at '='

At the moment it seems the parser chokes so much that it doesn't seem possible to even skip() these declarations, so you have to do something like:

infoMap.put(new Info("basename.hpp").linePatterns("\\s*const auto.*", ".*;\\s*").skip())

I think ideally these would be parsed, and if it was an unambiguous literal, type inference performed, otherwise cppTypes required before conversion.

This is used in OpenPose, which I'm currently wrapping and also used in gapi https://github.com/bytedeco/javacpp-presets/issues/780

Thanks for reporting! I've fixed that in the last commit, so please give it a try with 1.5.4-SNAPSHOT.

However, it won't try to deduce the type, so pretty much the only thing we can do at this stage is InfoMap.put(new Info("auto").skip()). We'll need to enhance this such that we can do things like InfoMap.put(new Info("FOO").cppTypes("int")), as it currently works for preprocessor macros...
