# FindGoogleBenchmark
# -----------------
#
# Try to locate the GoogleBenchmark source files, and then build them as a
# static library.
#
# The ``GOOGLEBENCHMARK_DIR`` (CMake or Environment) variable should be used
# to pinpoint the GoogleBenchmark source files.
#
# If found, this will define the following variables:
#
# ``GoogleBenchmark_FOUND``
# True if the GoogleBenchmark source package has been found.
#
# ``GoogleBenchmark``
# Target compiled as static library.
