# This directory contains tests that run CMake to configure a project
# but do not actually build anything. To add a test:
#
# 1.) Add a subdirectory named for the test.
#
# 2.) Call add_RunCMake_test and pass the test directory name.
#
# 3.) Create a RunCMakeTest.cmake script in the directory containing
# include(RunCMake)
# run_cmake(SubTest1)
# ...
# run_cmake(SubTestN)
# where SubTest1..SubTestN are sub-test names each corresponding to
# an independent CMake run and project configuration.
#
# 3.) Create a CMakeLists.txt file in the directory containing
# cmake_minimum_required(...)
# project(${RunCMake_TEST} NONE) # or languages needed
# include(${RunCMake_TEST}.cmake)
# where "${RunCMake_TEST}" is literal. A value for RunCMake_TEST
# will be passed to CMake by the run_cmake macro when running each
# sub-test.
#
# 4.) Create a <SubTest>.cmake file for each sub-test named above
# containing the actual test code. Optionally create files
# containing expected test results:
# <SubTest>-result.txt = Process result expected if not "0"
# <SubTest>-stdout.txt = Regex matching expected stdout content
# <SubTest>-stderr.txt = Regex matching expected stderr content
# Note that trailing newlines will be stripped from actual test
# output before matching against the stdout and stderr expressions.
