# - Configure a project for testing with CTest/CDash
# Include this module in the top CMakeLists.txt file of a project to
# enable testing with CTest and dashboard submissions to CDash:
#   project(MyProject)
#   ...
#   include(CTest)
# The module automatically creates a BUILD_TESTING option that selects
# whether to enable testing support (ON by default).  After including
# the module, use code like
#   if(BUILD_TESTING)
#     # ... CMake code to create tests ...
#   endif()
# to creating tests when testing is enabled.
#
# To enable submissions to a CDash server, create a CTestConfig.cmake
# file at the top of the project with content such as
#   set(CTEST_PROJECT_NAME "MyProject")
#   set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC")
#   set(CTEST_DROP_METHOD "http")
#   set(CTEST_DROP_SITE "my.cdash.org")
#   set(CTEST_DROP_LOCATION "/submit.php?project=MyProject")
#   set(CTEST_DROP_SITE_CDASH TRUE)
# (the CDash server can provide the file to a project administrator
# who configures 'MyProject').
# Settings in the config file are shared by both this CTest module and
# the CTest command-line tool's dashboard script mode (ctest -S).
#
# While building a project for submission to CDash, CTest scans the
# build output for errors and warnings and reports them with
# surrounding context from the build log.  This generic approach works
# for all build tools, but does not give details about the command
# invocation that produced a given problem.  One may get more detailed
# reports by adding
#   set(CTEST_USE_LAUNCHERS 1)
# to the CTestConfig.cmake file.  When this option is enabled, the
# CTest module tells CMake's Makefile generators to invoke every
# command in the generated build system through a CTest launcher
# program.  (Currently the CTEST_USE_LAUNCHERS option is ignored on
# non-Makefile generators.)  During a manual build each launcher
# transparently runs the command it wraps.  During a CTest-driven
# build for submission to CDash each launcher reports detailed
# information when its command fails or warns.
# (Setting CTEST_USE_LAUNCHERS in CTestConfig.cmake is convenient, but
# also adds the launcher overhead even for manual builds.  One may
# instead set it in a CTest dashboard script and add it to the CMake
# cache for the build tree.)
