Hi John,

No, the dynamic libraries are not. The import libraries are, however.

Ok, got that. This was why I was asking, because the CMake script I
currently use do this. Probably because the makers use mingw, where the
website states auto-linking doesn't work... So the authors might be
unaware of the problem.

I already did the former. Basically, I'm pulling in dependencies from
some other library which depends on boost. So when I include its
required libraries in my CMake script, the variable will contain boost
as well...

I'm wondering about this one. Basically, my situation is like this:

I have debug and release builds of dynamic and import boost libs. I
built the intermediate library (the one from above) using release. Now,
when I compile my own project for debug, the executable will crash
(within a function of the intermediate library). However, when I compile
my project for release, everything goes smoothly.
Would this be the kind of situation you mentioned above? Because I'm not
quite sure where this problem would be coming from, seeing as the
executables only require the correct libraries, i.e. my debug executable
will use boost debug libraries, and release libraries of my other
dependent library. Whereas release will require release boost libs and
release dependency... The exception I encounter in debug is actually
boost::thread::interrupted_exception, IIRC.
