# "Universal" Dashboard Script
#
# This script contains basic dashboard driver code common to all
# clients and projects.  It is a combination of the universal.cmake script in
# the Kitware DashboardScriptsNG repo and cmake_common.cmake used by CMake
# dashboards.
#
# Create a project-specific common script with code of the following form,
# where the final line includes this script.
#
#   set(CTEST_PROJECT_NAME "OpenChemistry")
#   set(CTEST_DROP_SITE "cdash.openchemistry.org")
#
#   set(dashboard_git_url "git://source.openchemistry.org/openchemistry.git")
#   set(dashboard_root_name "MyTests")
#   set(dashboard_source_name "openchemistry")
#
#   get_filename_component(dir ${CMAKE_CURRENT_LIST_FILE} PATH)
#   include(${dir}/universal.cmake)
#
# The following variables may be set before including this script
# to configure it:
#
#   dashboard_model       = Nightly | Experimental
#   dashboard_root_name   = Change name of "My Tests" directory
#   dashboard_source_name = Name of source directory (CMake)
#   dashboard_binary_name = Name of binary directory (CMake-build)
#   dashboard_cache       = Initial CMakeCache.txt file content

#   dashboard_do_checkout  = True to enable source checkout via git
#   dashboard_do_configure = True to enable the Configure step
#   dashboard_do_build     = True to enable the Build step
#   dashboard_do_test      = True to enable the Test step
#   dashboard_do_coverage  = True to enable coverage (ex: gcov)
#   dashboard_do_memcheck  = True to enable memcheck (ex: valgrind)

#   CTEST_GIT_COMMAND     = path to git command-line client
#   CTEST_BUILD_FLAGS     = build tool arguments (ex: -j2)
#   CTEST_DASHBOARD_ROOT  = Where to put source and build trees
#   CTEST_TEST_CTEST      = Whether to run long CTestTest* tests
#   CTEST_TEST_TIMEOUT    = Per-test timeout length
#   CTEST_TEST_ARGS       = ctest_test args (ex: PARALLEL_LEVEL 4)
#   CMAKE_MAKE_PROGRAM    = Path to "make" tool to use
#
# Options to configure Git:
#   dashboard_git_url      = Custom git clone url
#   dashboard_git_branch   = Custom remote branch to track
#   dashboard_git_crlf     = Value of core.autocrlf for repository
#
# For Makefile generators the script may be executed from an
# environment already configured to use the desired compilers.
# Alternatively the environment may be set at the top of the script:
#
#   set(ENV{CC}  /path/to/cc)   # C compiler
#   set(ENV{CXX} /path/to/cxx)  # C++ compiler
#   set(ENV{FC}  /path/to/fc)   # Fortran compiler (optional)
#   set(ENV{LD_LIBRARY_PATH} /path/to/vendor/lib) # (if necessary)
