# This CMake module will try to find SeqAn and its dependencies.  You can use
# it the same way you would use any other CMake module.
#
#   find_package(SeqAn [REQUIRED] ...)
#
# SeqAn has some optional dependencies that you must search for **before**
# you search for SeqAn:
#
#   ZLIB    -- zlib compression library
#   BZip2   -- libbz2 compression library
#   OpenMP  -- OpenMP language extensions to C/C++
#
# E.g.
#   find_package (ZLIB)
#   find_package (BZip2)
#   find_package (SeqAn [REQUIRED] ...)
#
# Once the search has been performed, the following variables will be set.
#
#  SEQAN_FOUND           -- Indicate whether SeqAn was found.
#
# (the dependencies have their own *_FOUND  variables, but inside the code we
# also define the following macros to indicate whether dependencies were found:
# of the SeqAn library were found.
#
#  SEQAN_HAS_ZLIB
#  SEQAN_HAS_BZIP2
#  SEQAN_HAS_OPENMP
#
# These variables give lists that are to be passed to the
# include_directories(), target_link_libraries(), and add_definitions()
# functions.
#
#  SEQAN_INCLUDE_DIRS
#  SEQAN_LIBRARIES
#  SEQAN_DEFINITIONS
#
# The C++ compiler flags to set.
#
#  SEQAN_CXX_FLAGS
#
# The following variables give the version of the SeqAn library, its
# major, minor, and the patch version part of the version string.
#
#  SEQAN_VERSION_STRING
#  SEQAN_VERSION_MAJOR
#  SEQAN_VERSION_MINOR
#  SEQAN_VERSION_PATCH
