Boost.Test and CMake

Applications Programming
1

Hi,
I just started using CMake and the Boost Libraries. In this progress I encountered some problems.
One of these problems is combining Boost unit tests with cmake. I don't know how to set the whole project up. I tried to set up a simple test project. This contains a main.cpp a comp.cpp and the comp.h
The main.cpp isn't doing anything at the moment. Comp contains a class:

class Comp
{
int add(int a, int b);
int sub(int a, int b);
}

Well the content of the cpp should be obvious I hope.
Additional I wrote the runner.cpp:

#define BOOST_TEST_MODULE "C++ Unit Tests for Calculator"
#include <boost/test/unit_test.hpp>
#include "Comp_Test.h"

and the Comp_Test.h:

#include <boost/test/unit_test.hpp>
#include"inc/Comp.h"
BOOST_AUTO_TEST_SUITE(adder_test_suite);
BOOST_AUTO_TEST_CASE(add_test_case)
{
        Adder adder;
        BOOST_REQUIRE_EQUAL(adder.add(10,5),15);
}
BOOST_AUTO_TEST_SUITE_END();

The folder structure is as followed:
main
|prog
| |inc
| | |Comp.h
| |main.cpp
| |Comp.cpp
| |CMakelists.txt[1]
|test
| |inc
| | |Comp_Test.h
| |runner.cpp
| |CMakelists.txt[2]

CMakelists.txt[1] should set up the makefile for the project itself and has following content:

cmake_minimum_required(VERSION 2.6)
project(comp)

ENABLE_TESTING()

include_directories(inc)

add_executable(prog
        main.cpp
        Comp.cpp
)
ADD_TEST(test1 TEST_BINARY_DIRECTORY comp_test)

and the second CMakelists.txt contains:

cmake_minimum_required(VERSION 2.6)
project(Test)
find_package(Boost REQUIRED unit_test_framework)

include_directories(inc)

include_directories(../prog)

include_directories(${Boost_INCLUDE_DIRS})
link_directories(${Boost_LIBRARY_DIRS})

add_executable(test
        runner.cpp)

target_link_libraries(
        test
        ${Boost_LIBRARIES}
)

So far am I. I think this contains some errors.
Some questions I couldn't answer myself:

  1. Is it even possible to separate this in 2 projects like I tried?
  2. If I don't separate it what happens to the testcode when I don't want to test? I hope it will only be executed if I execute "make test".

Well, sorry for the long code I hope somebody can help me. Thank you in advance for everybody who has taken the effort to read till the end. :slight_smile:
