Add CMake script to generate ctest definitions from Catch tests (#879)
Added cmake script to parse the source files containing Catch's test and generate ctest definitions. It generates one ctest test per `TEST_CASE` and labels them, using the `TEST_CASE`'s tags. Closes #719.

# Usage #
|
||||
# 1. make sure this module is in the path or add this otherwise: #
|
||||
# set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake.modules/") #
|
||||
# 2. make sure that you've enabled testing option for the project by the call: #
|
||||
# enable_testing() #
|
||||
# 3. add the lines to the script for testing target (sample CMakeLists.txt): #
|
||||
# project(testing_target) #
|
||||
# set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake.modules/") #
|
||||
# enable_testing() #
|
||||
# #
