| # 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() # |
