[CMake] CMAKE_xxx_LIBRARY_PREFIX

>From my "very first" today experience giving up the 'lib' prefix
is OK with mingw on a windows box (did not try a cross compiler though)

Moreover, from the MinGW documentation you have:
http://www.mingw.org/docs.shtml#compilingandbuilding

===
 To create the dll and an executable that uses it, try the following:
   gcc -c hello.c
   gcc -c -DBUILD_DLL dllfct.c
   gcc -shared -o tst.dll -Wl,--out-implib,libtstdll.a dllfct.o
   gcc -o hello.exe hello.o -L./ -ltst
===

One more clear from GNU binutils specific win32 gnu ld behavior
one can read:
http://sourceware.org/binutils/docs-2.18/ld/WIN32.html#WIN32


direct linking to a dll
[...]
    Linking directly to a dll uses no extra command-line switches
other than -L and -l, because ld already searches for a number of
names to match each library.
[...]

    For instance, when ld is called with the argument -lxxx it will
attempt to find, in the first directory of its search path,

    libxxx.dll.a
    xxx.dll.a
    libxxx.a
    cygxxx.dll (*)
    libxxx.dll
    xxx.dll

I really think it's safe when both WIN32 and MINGW to set the lib prefix to "".
I think that using this I may build more consistent DLL name.
