# - Find Assimp Installation
#
# Users can set the following variables before calling the module:
#  ASSIMP_DIR - The preferred installation prefix for searching for ASSIMP. Set by the user.
#
# ASSIMP_ROOT_DIR - the root directory where the installation can be found
# ASSIMP_CXX_FLAGS - extra flags for compilation
# ASSIMP_LINK_FLAGS - extra flags for linking
# ASSIMP_INCLUDE_DIRS - include directories
# ASSIMP_LIBRARY_DIRS - link directories
# ASSIMP_LIBRARIES - libraries to link plugins with
# ASSIMP_Boost_VERSION - the boost version assimp was compiled with
