如何将构建期间生成的文件添加到我的包含目录？

我正在尝试使用Python脚本为C ++代码生成一些头文件和源文件，并将它们移动到适当的源目录，因为后续的C ++构建需要它们。

这是我当前代码的迭代形式：

# Generate the Parameters and ParamParser files.
add_custom_command(
  OUTPUT include/waveparameters.h
         include/waveparser.h
         src/waveparser.cpp
  DEPENDS ${PROJECT_SOURCE_DIR}/scripts/wave.json
  COMMAND python3 ${CMAKE_SOURCE_DIR}/scripts/genParams.py ${CMAKE_CURRENT_SOURCE_DIR}/scripts/wave.json
  COMMENT "Generating custom Parameters files"
  VERBATIM USES_TERMINAL
)

add_custom_target(PAR_GENERATION
  DEPENDS include/waveparameters.h
          include/waveparser.h
          src/waveparser.cpp
)

set(MULTIGRID_INCLUDE_FILES
    include/waveparameters.h
    include/firstorderwave.h
    include/waveparser.h
   )
set(MULTIGRID_SOURCE_FILES
    src/multiGridTest.cpp
    src/firstorderwave.cpp
    src/waveparser.cpp
   )

set(SOURCE_FILES ${MULTIGRID_INCLUDE_FILES} ${MULTIGRID_SOURCE_FILES})
add_executable(MultiGridTest ${SOURCE_FILES})
target_include_directories(MultiGridTest PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/include)
target_include_directories(MultiGridTest PRIVATE ${CMAKE_SOURCE_DIR}/include)
target_link_libraries(MultiGridTest oops ${EXTRA_LIBS} m)

当前的代码生成效果很好。

但是，无论我为输出指定哪个目录（包括${CMAKE_CURRENT_SOURCE_DIR}/include或${CMAKE_SOURCE_DIR}/MultiGrid/include和相关路径），生成的.h和.cpp文件始终移至二进制文件生成的目录中：

${CMAKE_SOURCE_DIR}/build/MultiGrid

而不是 ：

${CMAKE_SOURCE_DIR}MultiGrid/include` and `${CMAKE_SOURCE_DIR}/MultiGrid/src
