FindSDL2
--------
Locate SDL2 library
This module defines the following 'IMPORTED' targets:
::
SDL2::Core
The SDL2 library, if found.
Libraries should link to SDL2::Core
SDL2::Main
The SDL2main library, if found.
Applications should link to SDL2::Main instead of SDL2::Core
This module will set the following variables in your project:
::
SDL2_LIBRARIES, the name of the library to link against
SDL2_INCLUDE_DIRS, where to find SDL.h
SDL2_FOUND, if false, do not try to link to SDL2
SDL2MAIN_FOUND, if false, do not try to link to SDL2main
SDL2_VERSION_STRING, human-readable string containing the version of SDL2
This module responds to the following cache variables:
::
SDL2_PATH
Set a custom SDL2 Library path (default: empty)
SDL2_NO_DEFAULT_PATH
Disable search SDL2 Library in default path.
If SDL2_PATH (default: ON)
Else (default: OFF)
SDL2_INCLUDE_DIR
SDL2 headers path.
SDL2_LIBRARY
SDL2 Library (.dll, .so, .a, etc) path.
SDL2MAIN_LIBRAY
SDL2main Library (.a) path.
SDL2_BUILDING_LIBRARY
This flag is useful only when linking to SDL2_LIBRARIES insead of
SDL2::Main. It is required only when building a library that links to
SDL2_LIBRARIES, because only applications need main() (No need to also
link to SDL2main).
If this flag is defined, then no SDL2main will be added to SDL2_LIBRARIES
and no SDL2::Main target will be created.
Don't forget to include SDLmain.h and SDLmain.m in 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 in your project
configuration, it means CMake did not find your SDL2 library
(SDL2.dll, libsdl2.so, SDL2.framework, etc). Set SDL2_LIBRARY 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_LIBRARIES variable and the
SDL2::Core and SDL2::Main targets, but when these values are unset,
SDL2_LIBRARIES, SDL2::Core and SDL2::Main 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
Created by Amine Ben Hassouna:
Adapt FindSDL.cmake to SDL2 (FindSDL2.cmake).
Add cache variables for more flexibility:
SDL2_PATH, SDL2_NO_DEFAULT_PATH (for details, see doc above).
Mark 'Threads' as a required dependency for non-OSX systems.
Modernize the FindSDL2.cmake module by creating specific targets:
SDL2::Core and SDL2::Main (for details, see doc above).
Original FindSDL.cmake module:
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 SDLmain 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 value of SDL2_LIBRARY to
override this selection or set the SDL2_PATH variable or the CMake
environment CMAKE_INCLUDE_PATH to modify the search paths.
Note that the header path has changed from SDL/SDL.h to just SDL.h
This needed to change because "proper" SDL convention is #include
"SDL.h", not <SDL/SDL.h>. This is done for portability reasons
because not all systems place things in SDL/ (see FreeBSD).

FindSDL2_image
--------------
Locate SDL2_image library
This module defines the following 'IMPORTED' target:
::
SDL2::Image
The SDL2_image library, if found.
Have SDL2::Core as a link dependency.
This module will set the following variables in your project:
::
SDL2_IMAGE_LIBRARIES, the name of the library to link against
SDL2_IMAGE_INCLUDE_DIRS, where to find the headers
SDL2_IMAGE_FOUND, if false, do not try to link against
SDL2_IMAGE_VERSION_STRING - human-readable string containing the
version of SDL2_image
This module responds to the following cache variables:
::
SDL2_IMAGE_PATH
Set a custom SDL2_image Library path (default: empty)
SDL2_IMAGE_NO_DEFAULT_PATH
Disable search SDL2_image Library in default path.
If SDL2_IMAGE_PATH (default: ON)
Else (default: OFF)
SDL2_IMAGE_INCLUDE_DIR
SDL2_image headers path.
SDL2_IMAGE_LIBRARY
SDL2_image Library (.dll, .so, .a, etc) path.
Additional Note: If you see an empty SDL2_IMAGE_LIBRARY in your project
configuration, it means CMake did not find your SDL2_image library
(SDL2_image.dll, libsdl2_image.so, etc). Set SDL2_IMAGE_LIBRARY to point
to your SDL2_image library, and configure again. This value is used to
generate the final SDL2_IMAGE_LIBRARIES variable and the SDL2::Image target,
but when this value is unset, SDL2_IMAGE_LIBRARIES and SDL2::Image does not
get created.
$SDL2IMAGEDIR is an environment variable that would correspond to the
./configure --prefix=$SDL2IMAGEDIR used in building SDL2_image.
$SDL2DIR is an environment variable that would correspond to the
./configure --prefix=$SDL2DIR used in building SDL2.
Created by Amine Ben Hassouna:
Adapt FindSDL_image.cmake to SDL2_image (FindSDL2_image.cmake).
Add cache variables for more flexibility:
SDL2_IMAGE_PATH, SDL2_IMAGE_NO_DEFAULT_PATH (for details, see doc above).
Add SDL2 as a required dependency.
Modernize the FindSDL2_image.cmake module by creating a specific target:
SDL2::Image (for details, see doc above).
Original FindSDL_image.cmake module:
Created by Eric Wing. This was influenced by the FindSDL.cmake
module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).

FindSDL2_ttf
------------
Locate SDL2_ttf library
This module defines the following 'IMPORTED' target:
::
SDL2::TTF
The SDL2_ttf library, if found.
Have SDL2::Core as a link dependency.
This module will set the following variables in your project:
::
SDL2_TTF_LIBRARIES, the name of the library to link against
SDL2_TTF_INCLUDE_DIRS, where to find the headers
SDL2_TTF_FOUND, if false, do not try to link against
SDL2_TTF_VERSION_STRING - human-readable string containing the
version of SDL2_ttf
This module responds to the following cache variables:
::
SDL2_TTF_PATH
Set a custom SDL2_ttf Library path (default: empty)
SDL2_TTF_NO_DEFAULT_PATH
Disable search SDL2_ttf Library in default path.
If SDL2_TTF_PATH (default: ON)
Else (default: OFF)
SDL2_TTF_INCLUDE_DIR
SDL2_ttf headers path.
SDL2_TTF_LIBRARY
SDL2_ttf Library (.dll, .so, .a, etc) path.
Additional Note: If you see an empty SDL2_TTF_LIBRARY in your project
configuration, it means CMake did not find your SDL2_ttf library
(SDL2_ttf.dll, libsdl2_ttf.so, etc). Set SDL2_TTF_LIBRARY to point
to your SDL2_ttf library, and configure again. This value is used to
generate the final SDL2_TTF_LIBRARIES variable and the SDL2::TTF target,
but when this value is unset, SDL2_TTF_LIBRARIES and SDL2::TTF does not
get created.
$SDL2TTFDIR is an environment variable that would correspond to the
./configure --prefix=$SDL2TTFDIR used in building SDL2_ttf.
$SDL2DIR is an environment variable that would correspond to the
./configure --prefix=$SDL2DIR used in building SDL2.
Created by Amine Ben Hassouna:
Adapt FindSDL_ttf.cmake to SDL2_ttf (FindSDL2_ttf.cmake).
Add cache variables for more flexibility:
SDL2_TTF_PATH, SDL2_TTF_NO_DEFAULT_PATH (for details, see doc above).
Add SDL2 as a required dependency.
Modernize the FindSDL2_ttf.cmake module by creating a specific target:
SDL2::TTF (for details, see doc above).
Original FindSDL_ttf.cmake module:
Created by Eric Wing. This was influenced by the FindSDL.cmake
module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).

# SDL2 CMake modules
This repository contains [CMake][] modules for finding and using the SDL2
library as well as other related libraries:
- [SDL2][]
- [SDL2_image][]
- [SDL2_ttf][]
- [SDL2_net][]
- [SDL2_mixer][]
- [SDL2_gfx][]
These modules are based on the SDL (1.2) modules, with the same names,
distributed with the CMake project. The SDL2_gfx module is also based
on the SDL_image module.
## Details and Improvements
The improvements made to these modules are as follows:
**FindSDL2.cmake**
- Adapt `FindSDL.cmake` to `SDL2` (`FindSDL2.cmake`).
- Add cache variables for more flexibility:<br>
`SDL2_PATH`, `SDL2_NO_DEFAULT_PATH`
- Mark `Threads` as a required dependency for non-OSX systems.
- Modernize the `FindSDL2.cmake` module by creating specific targets:
- `SDL2::Core` : Library project should link to `SDL2::Core`
- `SDL2::Main` : Application project should link to `SDL2::Main`
*For more details, please see the embedded documentation in `FindSDL2.cmake` file.*
**FindSDL2_&lt;COMPONENT&gt;.cmake**
- Adapt `FindSDL_<COMPONENT>.cmake` to `SDL2_<COMPONENT>` (`FindSDL2_<COMPONENT>.cmake`).
- Add cache variables for more flexibility:<br>
`SDL2_<COMPONENT>_PATH`, `SDL2_<COMPONENT>_NO_DEFAULT_PATH`
- Add `SDL2` as a required dependency.
- Modernize the `FindSDL2_<COMPONENT>.cmake` modules by creating specific targets:<br>
`SDL2::Image`, `SDL2::TTF`, `SDL2::Net`, `SDL2::Mixer` and `SDL2::GFX`.
*For more details, please see the embedded documentation in
`FindSDL2_<COMPONENT>.cmake` file.*
## Usage
In order to use the SDL2 CMake modules, we have to clone this repository in a
sud-directory `cmake/sdl2` in our project as follows:
```sh
cd <PROJECT_DIR>
git clone https://gitlab.com/aminosbh/sdl2-cmake-modules.git cmake/sdl2
rm -rf cmake/sdl2/.git
```
Or if we are using git for our project, we can add this repository as a
submodule as follows:
```sh
cd <PROJECT_DIR>
git submodule add https://gitlab.com/aminosbh/sdl2-cmake-modules.git cmake/sdl2
git commit -m "Add SDL2 CMake modules"
```
Then we should specify the modules path in the main CMakeLists.txt file like
the following:
```cmake
list(APPEND CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/cmake/sdl2)
```
Finally, we can use the SDL2 modules. There is two approaches that can be
adopted: A legacy approach and a modern approach. Both of them are supported.
### Modern CMake
We can link to the SDL2:: targets like the following example:<br>
*This example requires the SDL2, SDL2_image and the SDL2_gfx libraries*
```cmake
# Find SDL2, SDL2_image and SDL2_gfx libraries
find_package(SDL2 REQUIRED)
find_package(SDL2_image REQUIRED)
find_package(SDL2_gfx REQUIRED)
# Link SDL2::Main, SDL2::Image and SDL2::GFX to our project
target_link_libraries(${PROJECT_NAME} SDL2::Main SDL2::Image SDL2::GFX)
```
*Use the appropriate packages for you project.*<br>
*Please see above, for the whole list of packages*<br>
*For more details, please see the embedded documentation in modules files*
### Legacy CMake
We can also specify manually the include directories and libraries to link to:
```cmake
# Find and link SDL2
find_package(SDL2 REQUIRED)
target_include_directories(${PROJECT_NAME} PRIVATE ${SDL2_INCLUDE_DIRS})
target_link_libraries(${PROJECT_NAME} ${SDL2_LIBRARIES})
# Find and link SDL2_image
find_package(SDL2_image REQUIRED)
target_include_directories(${PROJECT_NAME} PRIVATE ${SDL2_IMAGE_INCLUDE_DIRS})
target_link_libraries(${PROJECT_NAME} ${SDL2_IMAGE_LIBRARIES})
# Find and link SDL2_gfx
find_package(SDL2_gfx REQUIRED)
target_include_directories(${PROJECT_NAME} PRIVATE ${SDL2_GFX_INCLUDE_DIRS})
target_link_libraries(${PROJECT_NAME} ${SDL2_GFX_LIBRARIES})
```
*For more details, please see the embedded documentation in modules files*
## Special customization variables
Each module have special customization cache variables that can be used to help
the modules find the appropriate libraries:
- `SDL2_PATH` and `SDL2_<COMPONENT>_PATH`:<br>
Can be specified to set the root search path for the `SDL2` and `SDL2_<COMPONENT>`
- `SDL2_NO_DEFAULT_PATH` and `SDL2_<COMPONENT>_NO_DEFAULT_PATH`:<br>
Disable search `SDL2/SDL2_<COMPONENT>` library in default path:<br>
If `SDL2[_<COMPONENT>]_PATH` is set, defaults to ON<br>
Else defaults to OFF
- `SDL2_INCLUDE_DIR` and `SDL2_<COMPONENT>_INCLUDE_DIR`:<br>
Set headers path. (Override)
- `SDL2_LIBRARY` and `SDL2_<COMPONENT>_LIBRARY`:<br>
Set the library (.dll, .so, .a, etc) path. (Override)
- `SDL2MAIN_LIBRAY`:<br>
Set the `SDL2main` library (.a) path. (Override)
These variables could be used in case of Windows projects, and when the
libraries are not localized in a standard pathes. They can be specified when
executing the `cmake` command or when using the [CMake GUI][] (They are marked
as advanced).
**cmake command example:**
```sh
mkdir build
cd build
cmake .. -DSDL2_PATH="/path/to/sdl2"
```
**CMakeLists.txt example:**
If we embed, for example, binaries of the SDL2_ttf in our project, we can
specify the cache variables values just before calling the `find_package`
command as follows:
```cmake
set(SDL2_TTF_PATH "/path/to/sdl2_ttf" CACHE BOOL "" FORCE)
find_package(SDL2_ttf REQUIRED)
```
