CMake: Project structure with unit tests

Question

I am trying to structure my project to include the production sources (in src subfolder) and tests (in test subfolder). I am using CMake to build t

Answer 1

I like the example of @Fraser but would use the add_test command in the test/CMakeLists.txt and use enable_testing before add_subdirectory(test).

This way you can run your tests from the top-level build directory while specifying your tests in the test/CMakeLists.txt.

The result would look like this (I reused the example of @Fraser):

CMakeLists.txt

cmake_minimum_required (VERSION 2.8)
project (TEST)
add_subdirectory (src)

enable_testing ()
add_subdirectory (test)

src/CMakeLists.txt

add_library (Sqr sqr.cpp sqr.h)
add_executable (demo main.cpp)
target_link_libraries (demo Sqr)

test/CMakeLists.txt

find_package (Boost COMPONENTS system filesystem unit_test_framework REQUIRED)
include_directories (${TEST_SOURCE_DIR}/src
                     ${Boost_INCLUDE_DIRS}
                     )
add_definitions (-DBOOST_TEST_DYN_LINK)
add_executable (Test test.cpp)
target_link_libraries (Test
                       Sqr
                       ${Boost_FILESYSTEM_LIBRARY}
                       ${Boost_SYSTEM_LIBRARY}
                       ${Boost_UNIT_TEST_FRAMEWORK_LIBRARY}
                       )
add_test (NAME MyTest COMMAND Test)
