# 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() #
|
|
# #
|
|
# find_path(CATCH_INCLUDE_DIR "catch.hpp") #
|
|
# include_directories(${INCLUDE_DIRECTORIES} ${CATCH_INCLUDE_DIR}) #

# file(GLOB SOURCE_FILES "*.cpp") #
