enabling optimisations of header only library for debug build

I'm using a header only library for a project (glm) and am currently trying to debug some problems I'm having. I trust that glm is giving me the correct values, however it is dog slow when built without optimisations (I'm using visual studio 2012/2013/2010 whichever is easiest to do this in, as all 3 are installed).

Is there a way to enable optimisations (specifically /O2), and disable debug symbols for just the GLM header files, while retaining the debug information for the rest of the solution?

EDIT:
I'd like to throw in, that I'd rather not change libraries at this point, as it's almost at the end of the project and I have other things to do aswell, so rewriting to use Eigen/CML isn't really on the table.

You can try:

1) Create one code file and include all headers you need.

2) Define all the template classes in this source file you want to use (e.g. "template ClassA;"

3) Compile this source File with optimization and link later against it.

4) Create a header file and declare all theses classes without the function definitions (simply copy the original header files and erase all functions definitions.)

5) Use this header file for your project.
