I am running Visual Studio 10 project, and I have some code that compiles fine. I have just recently included a third-party library with a header file. Now, every time I run my project, Visual Studio recompiles my source code, even when I do not make a single change to the code. It gives me this message in the output window: "Skipping... (no relevant changes detected)", but then, for whatever reason, takes ages to compile the code. (The header file that comes with the library is not that big anyway, so on another point, I am wondering why it is taking so long to compile.) Is there something that could be written into the header file or library that tells Visual Studio to recompile everything with each run? Any thoughts on what is going on here?
