Tempoary (!!!) workaround for incorrect key combination description in frontend This workaround fixes the incorrect string while preserving translations and the 1.0.0 string freeze. Remember to revert this commit and fix the string in binds.cpp after the 1.0.0 release!

# - Locate SDL2_ttf library
# This module defines:
#  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
#
# For backward compatiblity the following variables are also set:
#  SDL2TTF_LIBRARY (same value as SDL2_TTF_LIBRARIES)
#  SDL2TTF_INCLUDE_DIR (same value as SDL2_TTF_INCLUDE_DIRS)
#  SDL2TTF_FOUND (same value as SDL2_TTF_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).
