# This module defines
# SDL2_LIBRARY, the name of the library to link against
# SDL2_FOUND, if false, do not try to link to SDL2
# SDL2_INCLUDE_DIR, where to find SDL.h
#
# This module responds to the the flag:
# SDL2_BUILDING_LIBRARY
# If this is defined, then no SDL2main will be linked in because
# only applications need main().
# Otherwise, it is assumed you are building an application and this
# module will attempt to locate and set the the proper link flags
# as part of the returned SDL2_LIBRARY variable.
#
# Don't forget to include SDLmain.h and SDLmain.m your project for the
# OS X framework based version. (Other versions link to -lSDL2main which
# this module will try to find on your behalf.) Also for OS X, this
# module will automatically add the -framework Cocoa on your behalf.
#
#
# Additional Note: If you see an empty SDL2_LIBRARY_TEMP in your configuration
# and no SDL2_LIBRARY, it means CMake did not find your SDL2 library
# (SDL2.dll, libsdl2.so, SDL2.framework, etc).
# Set SDL2_LIBRARY_TEMP to point to your SDL2 library, and configure again.
# Similarly, if you see an empty SDL2MAIN_LIBRARY, you should set this value
# as appropriate. These values are used to generate the final SDL2_LIBRARY
# variable, but when these values are unset, SDL2_LIBRARY does not get created.
#
#
# $SDL2DIR is an environment variable that would
# correspond to the ./configure --prefix=$SDL2DIR
# used in building SDL2.
# l.e.galup 9-20-02
#
# Modified by Eric Wing.
# Added code to assist with automated building by using environmental variables
# and providing a more controlled/consistent search behavior.
# Added new modifications to recognize OS X frameworks and
# additional Unix paths (FreeBSD, etc).
# Also corrected the header search path to follow "proper" SDL guidelines.
# Added a search for SDL2main which is needed by some platforms.
# Added a search for threads which is needed by some platforms.
# Added needed compile switches for MinGW.
#
# On OSX, this will prefer the Framework version (if found) over others.
# People will have to manually change the cache values of
# SDL2_LIBRARY to override this selection or set the CMake environment
# CMAKE_INCLUDE_PATH to modify the search paths.
#
# Note that the header path has changed from SDL2/SDL.h to just SDL.h
# This needed to change because "proper" SDL convention
# is #include "SDL.h", not <SDL2/SDL.h>. This is done for portability
# reasons because not all systems place things in SDL2/ (see FreeBSD).

This repository contains CMake scripts for finding the `SDL2`, `SDL2_image` and
`SDL2_ttf` libraries and headers.
CMake itself comes with corresponding scripts for SDL 1.2, which hopefully in
time will be updated for SDL2 and make this repo redundant. In the mean
time, I'm putting them up here in case anyone else finds them useful.
I've tested them on Linux and Mac OS using the Makefile and XCode targets.
On Linux, you'll need the SDL2 development packages installed from your distro
package manager. On Mac OS you can install the development frameworks
from the SDL website or alternatively, if you use Homebrew you can run
`brew install sdl2` to install the development packages.
## Usage
### General
In order to use these scripts, you first need to tell CMake where to find them, via
the `CMAKE_MODULE_PATH` variable. For example, if you put them in a
subdirectory called `cmake`, then in your root `CMakeLists.txt` add the line
```cmake
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${project_SOURCE_DIR}/cmake")
```
where `project` is the name of your project. You can then use the packages
themselves by adding
```cmake
find_package(SDL2 REQUIRED)
find_package(SDL2_image REQUIRED)
find_package(SDL2_ttf REQUIRED)
include_directories(${SDL2_INCLUDE_DIR}
${SDL2_IMAGE_INCLUDE_DIR}
${SDL2_TTF_INCLUDE_DIR})
target_link_libraries(target ${SDL2_LIBRARY}
${SDL2_IMAGE_LIBRARIES}
${SDL2_TTF_LIBRARIES})
```
or whatever is appropriate for your project.
### mingw32 / msys
This section supplements ```Usage -> General``` section. You still are required
to incorporate ```General``` configuration settings in you CMakeLists.txt.
Because cmake binaries for windows aren't aware of *nix/win paths conversion,
default paths FindSDL2 will look in won't do any good. For that you should set SDL2_PATH variable.
For example:
```cmake
set(SDL2_PATH "D:\\apps\\SDL2\\i686-w64-mingw32")
```
```bash
mkdir build
cd build
cmake .. -G"MSYS Makefiles"
make
```
## Licence
I am not the original author of these scripts. I found `FindSDL2.cmake`
after some Googling, and hacked up the `image` and `ttf` scripts from the
