No tests were found

Hi, I'm trying to use CMakeCoverage.cmake together with Boost Unit test framework. I have several test modules and I'd like to aggregate the results, as described in #8.

So, I've written this code

include(CTest)
enable_testing()
include(CodeCoverage.cmake)
APPEND_COVERAGE_COMPILER_FLAGS()
set(COVERAGE_EXCLUDES 'external_dependencies/*')

add_subdirectory(${SRC_DIR} ${PROJECT_BINARY_DIR})

# Adding Unit-tests
add_test(NAME constant_neuron_test COMMAND constant_neuron_test)
add_test(NAME binary_neuron_test COMMAND binary_neuron_test)
add_test(NAME logistic_neuron_test COMMAND logistic_neuron_test)
add_test(NAME connectionFunctionGeneral_test COMMAND connectionFunctionGeneral_test)
add_test(NAME connection_Function_identity_test COMMAND connection_Function_identity_test)
add_test(NAME neural_network_test COMMAND neural_network_test)
add_test(NAME dataset_test COMMAND dataset_test)
add_test(NAME particle_swarm_test COMMAND particle_swarm_test)
add_test(NAME particle_test COMMAND particle_test)
add_test(NAME NeuralNetworkSum_test COMMAND NeuralNetworkSum_test)
add_test(NAME errorfunction_test COMMAND errorfunction_test)
add_test(NAME DESolver_test COMMAND DESolver_test)

SETUP_TARGET_FOR_COVERAGE_LCOV(
    NAME coverage
    EXECUTABLE ${CMAKE_CTEST_COMMAND})

The problem is, that something is wrong and I'm still getting the following error after running make coverage:

Do you know, what am I doing wrong?

If you'd like to see the whole project, its in git@code.it4i.cz:bes0030/4Neuro.git , in the branch coverage.

Thank you very much, Martin
