No - you will at least need FNT, SG and UL in addition to PUI.

It won't. PUI relies on FNT for rendering of text and on UL for directory
handling (file selector widget).

What have PUI's inter-PLIB dependancies to do with GLUT ? What's the
problem with them anyway ?

Nevertheless, you *can* tell PUI not to depend on GLUT at compile time if
you can live with some limitations. If compiled without GLUT, you will have
to feed PUI with window dimensions and font textures for now; additionally,
PUI currently won't allow you to spread user interface widgets across
different windows of your application.

For details, please see the PUI documentation (scroll down to the bottom of
the document):

Surely you are allowed to do so (as long as you do not remove the copyright
headers). Welcome in the world of the (L)GPL license !

I don't see any reason why you would want to do so.

Besides the fact that simply including all the C++ source files of PUI
won't work, the latter consits of about 9500 lines of code - including that
much text from each of your source files would slow down compilation of
your application in a serious extent. And finally, what is wrong with the
lib file ?

If the PLIB libraries are statically linked into your application binary,
it won't depend on the library files at runtime.
