在CMake中鏈接CxxTest，它表示成功但未能生成

Question

我剛剛下載了cxxtest的4.4版本，並將我的zip文件解壓縮到此路徑中：C：/cxxtest-4.4。 現在後，沒有做任何額外的步驟，我打開克利翁，並試圖CxxTest添加到我的項目，因爲它如下：

set(CXXTEST_PYTHON_TESTGEN_EXECUTABLE C:/cxxtest-4.4/python/cxxtest/cxxtestgen.py) 
find_package(CxxTest REQUIRED) 

if(CXXTEST_FOUND) 
    set(SOURCE_FILES main.cpp Calculator.h TestCalculator.h Calculator.cpp  TestCalculator.h) 
    add_executable(Calculator ${SOURCE_FILES}) 
endif() 

我不得不手動設置兩個變量會導致如果我不這麼做，我得到以下錯誤：

"C:\Program Files (x86)\JetBrains\CLion 2017.1\bin\cmake\bin\cmake.exe" -DCMAKE_BUILD_TYPE=Debug -G "CodeBlocks - MinGW Makefiles"  C:\Users\Admin\CLionProjects\Calculator

    CMakeLists.txt:9 (find_package) 


-- Configuring incomplete, errors occurred! 
See also "C:/Users/Admin/CLionProjects/Calculator/cmake-build- debug/CMakeFiles/CMakeOutput.log". 

現在一切似乎正常工作，這是我的CMake的調試：

"C:\Program Files (x86)\JetBrains\CLion 2017.1\bin\cmake\bin\cmake.exe" - DCMAKE_BUILD_TYPE=Debug -G "CodeBlocks - MinGW Makefiles"  C:\Users\Admin\CLionProjects\Calculator 
-- Configuring done 
-- Generating done 
-- Build files have been written to:  C:/Users/Admin/CLionProjects/Calculator/cmake-build-debug 

現在，當我嘗試使用cxxtest/TestSuite.h在一個頭文件裏面，它說它找不到它。這讓我瘋狂，請幫助我！

在此先感謝！

編輯：我設法連接它，現在我能找到的頭文件，添加到CMake的文件中這一行：當我建立我得到以下輸出

include_directories(C:/cxxtest-4.4) 

現在：

Answer 1

不確定這是否是一個問題，請參閱CxxTest的CMake文檔CMake文檔。

從您的示例CMakeLists文件看來，您做了正常項目文件的剪切和過去。您不能包含main.cpp文件CxxTest會根據您的測試定義文件生成一個名爲runner.cpp的文件。

所以在CMakeFiles.txt您CxxTest節應該是這個樣子：

set(CMAKE_PREFIX_PATH ${CMAKE_SOURCE_DIR}/deps/cxxtest/bin) 
find_package(CxxTest REQUIRED) 
if(CXXTEST_FOUND) 
    include_directories(${CXXTEST_INCLUDE_DIR}) 
    enable_testing() 
    CXXTEST_ADD_TEST(tests 
     runner.cpp # THIS IS GENERATED BUT YOU NEED TO ADD IT HERE 
     c:/libraries/boost_1_63_0/boost/filesystem.hpp # THIS SHOULD NOT BE HARD CODED 
     ${CMAKE_SOURCE_DIR}/source/string_tokenizer.cpp # YOUR PROJECT FILES THAT WILL BE USED FOR YOUR TEST 
     ${CMAKE_CURRENT_SOURCE_DIR}/tests/test_stringtokenizer.h # YOUR TEST DESCRIPTION FILE 
) 
    target_link_libraries(tests ${Boost_LIBRARIES}) # LINK BOOST/OTHER THIRD PARTY LIBS TO YOUR TEST 
endif() 

希望這有助於。
