WIP: make chat resizing faster
hold shift for pixel-precise size changes
# - Locate SDL2_mixer library# This module defines:# SDL2_MIXER_LIBRARIES, the name of the library to link against# SDL2_MIXER_INCLUDE_DIRS, where to find the headers# SDL2_MIXER_FOUND, if false, do not try to link against# SDL2_MIXER_VERSION_STRING - human-readable string containing the version of SDL2_mixer## For backward compatiblity the following variables are also set:# SDL2MIXER_LIBRARY (same value as SDL2_MIXER_LIBRARIES)# SDL2MIXER_INCLUDE_DIR (same value as SDL2_MIXER_INCLUDE_DIRS)# SDL2MIXER_FOUND (same value as SDL2_MIXER_FOUND)## $SDL2DIR is an environment variable that would# correspond to the ./configure --prefix=$SDL2DIR# used in building SDL2.## Created by Eric Wing. This was influenced by the FindSDL2.cmake# module, but with modifications to recognize OS X frameworks and# additional Unix paths (FreeBSD, etc).#=============================================================================# Copyright 2005-2009 Kitware, Inc.# Copyright 2012 Benjamin Eikel## Distributed under the OSI-approved BSD License (the "License");# see accompanying file Copyright.txt for details.## This software is distributed WITHOUT ANY WARRANTY; without even the# implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.# See the License for more information.#=============================================================================# (To distribute this file outside of CMake, substitute the full# License text for the above reference.)if(NOT SDL2_MIXER_INCLUDE_DIR AND SDL2MIXER_INCLUDE_DIR) set(SDL2_MIXER_INCLUDE_DIR ${SDL2MIXER_INCLUDE_DIR} CACHE PATH "directory cache entry initialized from old variable name")endif()find_path(SDL2_MIXER_INCLUDE_DIR SDL_mixer.h HINTS ENV SDL2MIXERDIR ENV SDL2DIR PATH_SUFFIXES include/SDL2 include)if(NOT SDL2_MIXER_LIBRARY AND SDL2MIXER_LIBRARY) set(SDL2_MIXER_LIBRARY ${SDL2MIXER_LIBRARY} CACHE FILEPATH "file cache entryinitialized from old variable name")endif()find_library(SDL2_MIXER_LIBRARY NAMES SDL2_mixer HINTS ENV SDL2MIXERDIR ENV SDL2DIR PATH_SUFFIXES lib)if(SDL2_MIXER_INCLUDE_DIR AND EXISTS "${SDL2_MIXER_INCLUDE_DIR}/SDL_mixer.h") file(STRINGS "${SDL2_MIXER_INCLUDE_DIR}/SDL_mixer.h" SDL2_MIXER_VERSION_MAJOR_LINE REGEX "^#define[ \t]+SDL_MIXER_MAJOR_VERSION[ \t]+[0-9]+$") file(STRINGS "${SDL2_MIXER_INCLUDE_DIR}/SDL_mixer.h" SDL2_MIXER_VERSION_MINOR_LINE REGEX "^#define[ \t]+SDL_MIXER_MINOR_VERSION[ \t]+[0-9]+$") file(STRINGS "${SDL2_MIXER_INCLUDE_DIR}/SDL_mixer.h" SDL2_MIXER_VERSION_PATCH_LINE REGEX "^#define[ \t]+SDL_MIXER_PATCHLEVEL[ \t]+[0-9]+$") string(REGEX REPLACE "^#define[ \t]+SDL_MIXER_MAJOR_VERSION[ \t]+([0-9]+)$" "\\1" SDL2_MIXER_VERSION_MAJOR "${SDL2_MIXER_VERSION_MAJOR_LINE}") string(REGEX REPLACE "^#define[ \t]+SDL_MIXER_MINOR_VERSION[ \t]+([0-9]+)$" "\\1" SDL2_MIXER_VERSION_MINOR "${SDL2_MIXER_VERSION_MINOR_LINE}") string(REGEX REPLACE "^#define[ \t]+SDL_MIXER_PATCHLEVEL[ \t]+([0-9]+)$" "\\1" SDL2_MIXER_VERSION_PATCH "${SDL2_MIXER_VERSION_PATCH_LINE}") set(SDL2_MIXER_VERSION_STRING ${SDL2_MIXER_VERSION_MAJOR}.${SDL2_MIXER_VERSION_MINOR}.${SDL2_MIXER_VERSION_PATCH}) unset(SDL2_MIXER_VERSION_MAJOR_LINE) unset(SDL2_MIXER_VERSION_MINOR_LINE) unset(SDL2_MIXER_VERSION_PATCH_LINE) unset(SDL2_MIXER_VERSION_MAJOR) unset(SDL2_MIXER_VERSION_MINOR) unset(SDL2_MIXER_VERSION_PATCH)endif()set(SDL2_MIXER_LIBRARIES ${SDL2_MIXER_LIBRARY})set(SDL2_MIXER_INCLUDE_DIRS ${SDL2_MIXER_INCLUDE_DIR})if(BUILD_ENGINE_JS) set(SDL2_MIXER_LIBRARY "sdl2_mixer_emscripten_internal") set(SDL2_MIXER_LIBRARIES "sdl2_mixer_emscripten_internal") set(SDL2_MIXER_INCLUDE_DIRS "${CMAKE_SYSTEM_INCLUDE_PATH}/SDL")endif()include(FindPackageHandleStandardArgs)FIND_PACKAGE_HANDLE_STANDARD_ARGS(SDL2_mixer REQUIRED_VARS SDL2_MIXER_LIBRARIES SDL2_MIXER_INCLUDE_DIRS VERSION_VAR SDL2_MIXER_VERSION_STRING)# for backward compatiblityset(SDLMIXER_LIBRARY ${SDL2_MIXER_LIBRARIES})set(SDLMIXER_INCLUDE_DIR ${SDL2_MIXER_INCLUDE_DIRS})set(SDLMIXER_FOUND ${SDL2_MIXER_FOUND})mark_as_advanced(SDL2_MIXER_LIBRARY SDL2_MIXER_INCLUDE_DIR)
