# Special comments:
#
# all targets in here should follow the same structure,
# and provide a get-a, extract-a, configure-a, compile-a, check-a, fastcheck-a, and install-a
# additionally all targets should be listed in the getall target for easier off-line compilation
# if you are adding a new target, it can help to copy an similar, existing target
#
# autoconf configure-driven scripts: llvm pcre unwind gmp mpfr patchelf libuv curl
# custom Makefile rules: openlibm dsfmt suitesparse-wrapper suitesparse lapack openblas utf8proc objconv osxunwind libwhich
# CMake libs: libgit2 libssh2 mbedtls
#
# downloaded from git: llvm-svn, libuv, libopenlibm, utf8proc, libgit2, libssh2
#
# there are rules in this file with the . replaced by a %
# this is some magic Makefile trick that tells make
# that all targets with a % in them on that line will
# be rebuilt in a single invocation
#
# to debug 'define' rules, replace eval at the usage site with info or error
#

## Overall configuration of which rules exist and should be run by default ##
