What I was trying to say is that you're hardcoding the lib name and 
version inside the code. I see two problems with this: if the pragma is 
in my code than I need to re-compile my code if I want to edit the 
pragma (rename lib, change version, change vendor, etc...)
if the pragma is in some 3rd party component which I don't have the 
source for than I can't change the pragma.
either way, it conflicts with my work-flow and goals.

I do not wish to recompile a 1.5GB standalone executable if I just 
changed a minor version of a lib.

IIRC, the math lib in C/C++ comes in three flavors so you can choose 
your trade-off (speed or accuracy) and the only thing you need to do is 
just link the flavor you want in your executable.

you seem keen on combining the build process with compilation which is 
in my experience a very bad thing. it may simplify your life for your 
small projects but as I was telling you before it's a pain in the neck 
for the scale of projects I work on. I don't get why you refuse to see 
that.
what you suggest is _not_ a good solution for me.
