FindSDL2_ttf
|
|
------------
|
|
|
|
Locate SDL2_ttf library
|
|
|
|
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, but when this value is
|
|
unset, SDL2_TTF_LIBRARIES 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.
|
|
|
|
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).
