CMake: Fix missing WIN32 definition on Windows platforms.

Browse Source 
Although some Windows compilers still #define WIN32, more and more
standard compliant compilers only #define _WIN32. FLTK *did* #define
WIN32 for all Windows targets with autoconf/configure, but that bit
was lost for CMake builds. This is necessary until we replace WIN32
with _WIN32 throughout the Windows specific code.
