我有一个有结构的项目

顶层目录CMakeLists.txt文件在哪里
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。添加它和 after 中的行tests/CMakeLists.txt之后# Communications test，runningctest没有做任何额外的事情——它仍然只运行第一个测试。
删除构建目录并cmake再次运行后，初始 CMake 运行没有错误，但运行make再次运行 CMake，导致 CMake 出错：
CMake Error: Parse error in cache file build/CMakeCache.txt. Offending entry: include
后跟一个 Make 错误：
Makefile:203: recipe for target 'cmake_check_build_system' failed
make: *** [cmake_check_build_system] Error 1
再次运行make会导致构建所有内容，包括测试；但是，运行ctest会导致
Test project build
No tests were found!!!
问题似乎与我正在使用 CMake 做的事情有关，但无法从这里弄清楚该怎么做，因为我看不到我正在做的任何事情与最初工作时不同。甚至我最后一次提交到 git 时，它在我提交时正在工作，现在也不再工作了。
