Instead of having to add a new feature you could add <cxxflags> and/or
<cflags> to the usage requirements.

I have the same goal in the third-party libs I use and build.

For the generation of the file itself take a look at the wxWidgets
support I wrote in the vault
It creates the wx/setup.h dynamically using the built in "make" target.
With the added <implicit-dependency> the directory where the generated
header is added to the include path automatically so you only need to
specify the name of the header file, without the path, in the flags. I
have more complicated example of using this technique to also generate
source files to compile that do things like predef and include other
sources so that I can do things like disable and rewrite parts of the
thrid-party libs.
