Something else is going on for you Mathieu, it works for me, see below.

It just does not seem that stable as people could have it on any drive. 
  However, it should not really hurt, and I don't think this is causing 
the trouble the Mathieu is reporting.

I finally tested this on my machine, and it works fine!

I installed wxWidgets 2.8.7 with the windows installer from the 
wxWidgets download.  Then I built it and ran
cmake_minimum_required(VERSION 2.6)

It found it just fine, and with the c:, as you can see:
(The  PATH_SUFFIXES  had not negative effect...)

//Set wxWidgets configuration (mswd)
//wxWidgets base/installation directory?
//Details about finding wxWidgets

Mathieu what is in your PATH?   The find stuff does search the PATH, 
perhaps there is something in your PATH that is causing this?

Other than that, I think you might have to put some print statements 
into CMake's cmFindBase.cxx and try to figure out how it is finding the 
non drive letter version of wxWidgets on your machine.
