CMake: Don't use /NODEFAULTLIB on Windows unless we're Visual Studio.

     5 By default SDL will only link against glibc, the rest of the features will be
     6 enabled dynamically at runtime depending on the available features on the target
     7 system. So, for example if you built SDL with Xinerama support and the target
     8 system does not have the Xinerama libraries installed, it will be disabled
     9 at runtime, and you won't get a missing library error, at least with the 
    10 default configuration parameters.

    17 Ubuntu 13.04, all available features enabled:
    18 
    19 sudo apt-get install build-essential mercurial make cmake autoconf automake \
    20 libtool libasound2-dev libpulse-dev libaudio-dev libx11-dev libxext-dev \
    21 libxrandr-dev libxcursor-dev libxi-dev libxinerama-dev libxxf86vm-dev \
    22 libxss-dev libgl1-mesa-dev libesd0-dev libdbus-1-dev libudev-dev \
    23 libgles1-mesa-dev libgles2-mesa-dev libegl1-mesa-dev
    24 
    25 NOTES:
    26 - This includes all the audio targets except arts, because Ubuntu pulled the 
    27   artsc0-dev package, but in theory SDL still supports it.
    28 - DirectFB isn't included because the configure script (currently) fails to find
    29   it at all. You can do "sudo apt-get install libdirectfb-dev" and fix the 
    30   configure script to include DirectFB support. Send patches.  :)

    37 If you compiled or are using a version of SDL with udev support (and you should!)
    38 there's a few issues that may cause SDL to fail to detect your joystick. To
    39 debug this, start by installing the evtest utility. On Ubuntu/Debian:
    40 
    41     sudo apt-get install evtest
    42     
    43 Then run:
    44     
    45     sudo evtest
    46     
    47 You'll hopefully see your joystick listed along with a name like "/dev/input/eventXX"
    48 Now run:
    49     
    50     cat /dev/input/event/XX
    51 
    52 If you get a permission error, you need to set a udev rule to change the mode of
    53 your device (see below)    
    54     
    55 Also, try:
    56     
    57     sudo udevadm info --query=all --name=input/eventXX
    58     
    59 If you see a line stating ID_INPUT_JOYSTICK=1, great, if you don't see it,
    60 you need to set up an udev rule to force this variable.
    61 
    62 A combined rule for the Saitek Pro Flight Rudder Pedals to fix both issues looks 
    63 like:
    64     
    65    SUBSYSTEM=="input", ATTRS{idProduct}=="0763", ATTRS{idVendor}=="06a3", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"
    66    SUBSYSTEM=="input", ATTRS{idProduct}=="0764", ATTRS{idVendor}=="06a3", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"
    67    
    68 You can set up similar rules for your device by changing the values listed in
    69 idProduct and idVendor. To obtain these values, try:
    70     
    71     sudo udevadm info -a --name=input/eventXX | grep idVendor
    72     sudo udevadm info -a --name=input/eventXX | grep idProduct
    73     
    74 If multiple values come up for each of these, the one you want is the first one of each.    
    75 
    76 On other systems which ship with an older udev (such as CentOS), you may need
    77 to set up a rule such as:
    78     
    79     SUBSYSTEM=="input", ENV{ID_CLASS}=="joystick", ENV{ID_INPUT_JOYSTICK}="1"
