+# - Find CxxTest
+# Find the CxxTest suite and declare a helper macro for creating unit tests
+# and integrating them with CTest. To assist in finding CxxTest the
+# CMAKE_PREFIX_PATH variable can be used.
+# For more details on CxxTest see http://cxxtest.tigris.org
+#
+# INPUT Variables
+#
+# CXXTEST_USE_PYTHON
+# If true, have the CXXTEST_ADD_TEST macro use
+# the python test generator instead of perl.
+#
+# OUTPUT Variables
+#
+# CXXTEST_INCLUDE_DIR
+# Where to find the CxxTest include directory
+# CXXTEST_FOUND
+# True if the CxxTest framework was found
+# CXXTEST_PERL_TESTGEN_EXECUTABLE
+# The perl-based test generator.
+# CXXTEST_PYTHON_TESTGEN_EXECUTABLE
+# The python-based test generator.
+#
+# MACROS for use by CMake users:
+#
+# CXXTEST_ADD_TEST(<test_name> <gen_source_file> <input_files_to_testgen...>)
+# Creates a CxxTest runner and adds it to the CTest testing suite
+# Parameters:
+# test_name The name of the test
+# gen_source_file The generated source filename to be generated by CxxTest
+# input_files_to_testgen The list of header files containing the
+# CxxTest::TestSuite's to be included in this runner
+#
+# Example:
+# ENABLE_TESTING()
+# CXXTEST_ADD_TEST(unittest_foo foo_test.cc ${CMAKE_CURRENT_SOURCE_DIR}/foo_test.h)
+#
+# This will:
+# 1. Invoke the testgen executable to autogenerate foo_test.cc in the
+# binary tree from "foo_test.h" in the current source directory.
+# 2. Create an executable and test called unittest_foo.
