CTest没有检测到测试

Question

我有一个带结构的项目

??? CMakeLists.txt
??? mzl.c
??? mzl.h
??? tests
    ??? CMakeLists.txt
    ??? mzl-communication-test.c
    ??? mzl-setup-test.c
    ??? mzl-test-errors.c
    ??? mzl-test-errors.h

顶级目录CMakeLists.txt文件的位置

project(mzl)
cmake_minimum_required(VERSION 2.8)

add_subdirectory(tests)

# Enable testing for the project
enable_testing()

# Find zmq
find_library(ZMQ_LIB zmq REQUIRED)
message(STATUS "ZMQ Library: ${ZMQ_LIB}")

# Find threading library
set(CMAKE_THREAD_PREFER_PTHREAD ON)
find_package(Threads REQUIRED)
message(STATUS "Threading Library: ${CMAKE_THREAD_LIBS_INIT}")



# Set include directories for headers
set     (
    MZL_INCLUDE_DIRS
    ${CMAKE_SOURCE_DIR}
    CACHE STRING "MZL Include Directories"
    )
include_directories(${MZL_INCLUDE_DIRS})

# Set source files
set     (
    MZL_SRC_FILES
    mzl.c
    )

# Add library
add_library(${PROJECT_NAME} STATIC ${MZL_SRC_FILES})

# Link to zmq
target_link_libraries(${PROJECT_NAME} ${ZMQ_LIB} ${CMAKE_THREAD_LIBS_INIT})

并且tests/CMakeLists.txt是

# Use MZL Source Directories (mzl headers are in top directory)
include_directories(${CMAKE_SOURCE_DIR})

# Variable from here is empty
message(STATUS "MZL Include Directories: ${MZL_INCLUDE_DIRS}")

# Files common to all tests
set ( TEST_COMMON_SOURCES
    mzl-test-errors.c
    )

# Library setup/shutdown testing
set(SETUP_TEST_NAME mzl-setup-test)
add_executable(${SETUP_TEST_NAME} ${TEST_COMMON_SOURCES} ${SETUP_TEST_NAME}.c)
target_link_libraries(${SETUP_TEST_NAME} ${PROJECT_NAME} ${ZMQ_LIB})
add_test(${SETUP_TEST_NAME} ${SETUP_TEST_NAME})

# Communcations test
set(COMMUNICATION_TEST_NAME mzl-communication-test)
add_executable(${COMMUNICATION_TEST_NAME} ${TEST_COMMON_SOURCES}
    ${COMMUNICATION_TEST_NAME}.c)
target_link_libraries(${COMMUNICATION_TEST_NAME} ${PROJECT_NAME}
        ${CMAKE_THREAD_LIBS_INIT} ${ZMQ_LIB})
add_test(${COMMUNICATION_TEST_NAME}  ${COMMUNICATION_TEST_NAME})

在我添加第二个测试之前,一切正常mzl-communication-test.在添加它和tests/CMakeLists.txt后面的行后# Communications test,运行ctest没有任何额外的 - 它仍然只运行第一次测试.

删除构建目录并cmake再次运行后,我没有得到初始CMake运行的错误,但是运行make再次运行CMake,导致CMake出错:

CMake Error: Parse error in cache file build/CMakeCache.txt. Offending entry: include

然后是Make错误:

Makefile:203: recipe for target 'cmake_check_build_system' failed
make: *** [cmake_check_build_system] Error 1

make再次运行会导致所有内容都被构建,包括测试; 但是,运行ctest结果

Test project build
No tests were found!!!

这个问题似乎与我在使用CMake做的事情有关,但无法弄清楚从这里做什么,因为我看不到任何与我最初工作时不同的事情.即使是我最后一次提交git,它在我提交它时工作,也不再有效.

您需要先转移enable_testing()呼叫add_subdirectory(tests)

# Enable testing for the project
enable_testing()

add_subdirectory(tests)
