1 # - Locate SDL2_ttf library |
|
2 # This module defines: |
|
3 # SDL2_TTF_LIBRARIES, the name of the library to link against |
|
4 # SDL2_TTF_INCLUDE_DIRS, where to find the headers |
|
5 # SDL2_TTF_FOUND, if false, do not try to link against |
|
6 # SDL2_TTF_VERSION_STRING - human-readable string containing the version of SDL2_ttf |
|
7 # |
|
8 # For backward compatiblity the following variables are also set: |
|
9 # SDL2TTF_LIBRARY (same value as SDL2_TTF_LIBRARIES) |
|
10 # SDL2TTF_INCLUDE_DIR (same value as SDL2_TTF_INCLUDE_DIRS) |
|
11 # SDL2TTF_FOUND (same value as SDL2_TTF_FOUND) |
|
12 # |
|
13 # $SDL2DIR is an environment variable that would |
|
14 # correspond to the ./configure --prefix=$SDL2DIR |
|
15 # used in building SDL2. |
|
16 # |
|
17 # Created by Eric Wing. This was influenced by the FindSDL2.cmake |
|
18 # module, but with modifications to recognize OS X frameworks and |
|
19 # additional Unix paths (FreeBSD, etc). |
