# upstream killed static lib support with build system update

# all test dependencies are optional:
|
|
|
|
|
# - gflags-2.2 is supposedly needed for command-line option parsing
|
|
|
|
|
# but it's a huge hack and does not work,
|
|
|
|
|
# - gtest probably gives nicer output,
|
|
|
|
|
# - compression libraries are used for benchmarks which we do not run.
