Subject: [PATCH] [msvc] Fix quoting of OSRM_PROJECT_DIR as preprocessor define

It looks MSVC still special handling, no quotoing as well as
additional quoting like add_definitions(-DFOO="\\"foo\\"")
as per https://cmake.org/pipermail/cmake/2007-June/014611.html
does not seem to handle CMake variables correctly.

This Visual C++ specific fix is based on this solution
