# This script is intended to be run as part of the cmake for the code project.

# It will download, build and install the google test library for use in

# test written using that framework.

#

# The source directory for Google Test will be code/gtest.  It will contain

# a single subdirectory (googletest-release-1.7.0 at this writing) which is

# the is the root of the exploded tar file.  The source directory will be

# added as a subdirectory of the project and thus contain a CMakeLists.txt 

# file.  This is created from the template file GoogleTestInstall.in.

# The header files needed for unit test compilation will remain in 

# the include folder of the release (i.e., they are not installed as other

# CASA include files are).

#

# As configured CMakeLists.txt file will create a corresponding binary directory

# (e.g., code/build/gtest).  The static libraray, libgtest.a, will be located

# there for use in building unit tests.  The library is actually built as part

# of the "make" process and the compilation should be using all the same settings

# as the other C++ files in code.

#

# The google test configuration will only be performed if the code/gtest directory

# is not present; thus to get a clean redo, that directory must first be removed.

#

# This framework was constructed 8 October 2015 when the current version of

# google test was 1.7.0 and recently relocated onto github.  The archive is

# found in the "release" section of the google/googletest repo.
