Thanks everyone for the help. I really have a typo in my CMake code so thanks
for every one for finding that. Basically we build a few libraries which other
parts of our code depend on. One particular library has to be a shared library
but links statically to the other libraries in order to avoid some STL issues
that are on VS 2008 and 2010. I bet these issues are not around on GCC with
Linux so I bet I need to basically put in a safeguard to only build shared
libraries on Linux and no-where else but I need to test that theory.
I like the source files properties idea but I would need to apply that to
just about every source file in our project. For now an all encompassing -fPIC
for everything should solve the issue for the moment until a better fix in the
form of a rewritten API can be put in.
Thanks everyone for helping
