I am trying to use CATCH unit test suite linked below. https://github.com/philsquared/Catch
However, I cannot succeed to make it right. The main.cpp and test.cpp are as follows.
//main.cpp
#define CATCH_CONFIG_MAIN
#include "catch.hpp"
//test.cpp
#include "catch.hpp"
TEST_CASE("TESTTest", "") {
CHECK(1 != 2 );
}
When this two files are located in the same folder, I could get a desired result.
However, I moved the test.cpp to the subdirectory named test. It does not work anymore as expected but generates linking errors.
My cmake setting is described below.
project(catchTest)
cmake_minimum_required(VERSION 2.8)
file(GLOB_RECURSE INCS "./*.cpp")
add_executable(${PROJECT_NAME} main.cpp ${INCS})
include_directories(.)
file(GLOB_RECURSE INCS "./*.cpp") was added to include every cpp source files located in the subdirectories. and include_directories(.) was included to let them know the definition of catch.hpp.
I am pretty shure I've done something wrong but I don't know how to fix it. Please advise me to solve this problem.
It was run on Windows, compiled using mingw gcc-4.9.1 and generated by cmake ninja generator.
EDIT : I added the first few lines of error messages.

Your CMakeLists.txt is wrong, it includes main twice. If you change the add_executable-statement like this it works for me:
add_executable(${PROJECT_NAME} main.cpp test.cpp )
Hope that helps.
