Fixing problem with .pdb files in Debug version

[ThibaultDECO]

• replacing the default /Zi in MSVC with /Z7, so that the debugging information ends up embedded in the .lib file rather than separate .pdb files.
• forcing cmake to override the default cache

Hi @ThibaultDECO - while my understanding of cmake is limited, do you still remember why you thought it was a good idea to have debug symbols included in the library binary? If MSVC offers to have debug information in separate files, why not make use of that?

Hi @aral-matrix
Unfortunately, I don't remember, it was too long time ago

Thanks for getting back to me / responding here anyways. Would you be okay to close (or for me to close) the pull request then?

I believe that your pull request implements something that was very specific to your use case, and even you yourself only needed it for debugging - so without really understanding the consequences or being able to properly test it, I would prefer to not accept this.
