# - Find CxxTest
# Find the CxxTest suite and declare a helper macro for creating unit tests
# and integrating them with CTest.
# For more details on CxxTest see http://cxxtest.tigris.org
#
# INPUT Variables
#
# CXXTEST_USE_PYTHON
# If true, the CXXTEST_ADD_TEST macro will use
# the Python test generator instead of Perl.
#
# OUTPUT Variables
#
# CXXTEST_FOUND
# True if the CxxTest framework was found
# CXXTEST_INCLUDE_DIR
# Where to find the CxxTest include directory
# 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 Usage:
#
# FIND_PACKAGE(CxxTest)
# INCLUDE_DIRECTORIES(${CXXTEST_INCLUDE_DIR})
#
# 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.
#
# #=============
# Example foo_test.h:
#
# #include <cxxtest/TestSuite.h>
#
# class MyTestSuite : public CxxTest::TestSuite
# {
# public:
# void testAddition( void )
# {
# TS_ASSERT( 1 + 1 > 1 );
# TS_ASSERT_EQUALS( 1 + 1, 2 );
# }
# };

# Version 1.0 (1/8/08)
# Fixed CXXTEST_INCLUDE_DIRS so it will work properly
# Eliminated superfluous CXXTEST_FOUND assignment
# Cleaned up and added more documentation
