## CMake
|
|
|
|
You can use the following CMake script to automatically fetch Catch from github and configure it as an external project:
|
|
|
|
```CMake
|
|
cmake_minimum_required(VERSION 2.8.8)
|
|
project(catch_builder CXX)
|
|
include(ExternalProject)
|
|
find_package(Git REQUIRED)
|
|
|
|
ExternalProject_Add(
|
|
catch
|
|
PREFIX ${CMAKE_BINARY_DIR}/catch
|
|
GIT_REPOSITORY https://github.com/philsquared/Catch.git
|
|
TIMEOUT 10
|
|
UPDATE_COMMAND ${GIT_EXECUTABLE} pull
|
|
CONFIGURE_COMMAND ""
|
|
BUILD_COMMAND ""
|
|
INSTALL_COMMAND ""
|
|
LOG_DOWNLOAD ON

|
)
|
|
|
|
# Expose required variable (CATCH_INCLUDE_DIR) to parent scope
|
|
ExternalProject_Get_Property(catch source_dir)
|
|
set(CATCH_INCLUDE_DIR ${source_dir}/include CACHE INTERNAL "Path to include folder for Catch")
|
|
```
|
|
|
|
If you put it in, e.g., `${PROJECT_SRC_DIR}/${EXT_PROJECTS_DIR}/catch/`, you can use it in your project by adding the following to your root CMake file:
|
|
|
|
```CMake
|
|
# Includes Catch in the project:
|
|
add_subdirectory(${EXT_PROJECTS_DIR}/catch)
|
|
include_directories(${CATCH_INCLUDE_DIR} ${COMMON_INCLUDES})
|
|
enable_testing(true) # Enables unit-testing.
|
|
```
