0002 #
0003 # Defines the following variables:
0004 # CLANG_FOUND - True if Clang was found
0005 # CLANG_INCLUDE_DIRS - Where to find Clang includes
0006 # CLANG_LIBRARY_DIRS - Where to find Clang libraries
0007 #
0008 # CLANG_LIBCLANG_LIB - Libclang C library
0009 #
0010 # CLANG_CLANGFRONTEND_LIB - Clang Frontend (C++) Library
0011 # CLANG_CLANGDRIVER_LIB - Clang Driver (C++) Library
0012 # ...
0013 #
0014 # CLANG_LIBS - All the Clang C++ libraries
0015 #
0016 # Uses the same include and library paths detected by FindLLVM.cmake
