Linking CxxTest in CMake, it says it succeeds but fails to build

I just downloaded version 4.4 of cxxtest and unpacked my zip file into this path: C:/cxxtest-4.4. Now immediately after, without doing any additional step I opened CLion and tried to add CxxTest to my project as it follows:

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()

I had to manually set the two variables cause if I don't i get the following error:

"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".

Now everything apparently works fine, and this is my Cmake debug:

"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

When now I try to use cxxtest/TestSuite.h inside an header file, it says it cannot find it. This is driving me crazy, please, I need your help!

Thanks in advance!

Edit: I managed to link it and now I can find the header files, adding to CMake file this line: 

include_directories(C:/cxxtest-4.4)

Now when I build I get the following output:

"C:\Program Files (x86)\JetBrains\CLion 2017.1\bin\cmake\bin\cmake.exe" --    build C:\Users\Admin\CLionProjects\Calculator\cmake-build-debug --target     Calculator -- -j 8

Not sure if this is sill a problem, look at the CMake documentation CMake documentation for CxxTest.

From your example CMakeLists file it seems you did a cut and past of your normal project files. You must not include the main.cpp file CxxTest generates a file called runner.cpp based on your test deffinition file(s).

So your CxxTest section in the CMakeFiles.txt should look something like this:

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()

Hope this helps.
