# Find ABC
# ABC_FOUND - system has ABC lib
# ABC_INCLUDE_DIR - the ABC include directory
# ABC_LIBRARIES - Libraries needed to use ABC
# ABC_ARCH_FLAGS - Platform specific compile flags

# Note: contrib/get-abc copies header files to deps/install/include/abc.
# However, includes in ABC headers are not prefixed with "abc/" and therefore
# we have to look for headers in include/abc instead of include/.
