# This module accepts the following env variable

# FREETYPE_SDK - Can be set to custom install path
|

#
|

# Once done, this will define

#
|

# FREETYPE_FOUND - system has FreeType
|

# FREETYPE_INCLUDE_DIRS - the FreeType include directories
|

# FREETYPE_LIBRARIES - link these to use FreeType

# Freetype_FOUND - system has FreeType
|

# Freetype_INCLUDE_DIRS - the FreeType include directories
|

# Freetype_LIBRARIES - link these to use FreeType

# Freetype_VERSION - version of FreeType
