When using Boost.Test, there is generally no need to define a main() function, since Boost.Test provides one itself.

I recently had to convert my project to use static linking of 3rd party libraries (on VS2010). Naturally, I had to link to multiple .libs so that the build succeeds, and my build ran just fine.

However, when I ran my test project, something really strange happened. It seems that one of the 3rd party .libs (libpng), required by one of my dependent libraries, contained a test file with a main() function defined within (pngtest.c). 

Since my project did not have a main() function, The linker chose that one as my "test" application. Thus, non of my tests run.

Does anyone know how I prevent this from happening? 

How can I tell the linker/compiler to use the Boost.Test main()?
