如何使用CMake将文件添加到非可执行或非库目标 [英] How to add files to a non-executable or non-library target with CMake

问题描述

我了解，如果目标是可执行文件或库，可以使用以下命令将某些文件添加到CMake中：

I understand I can add some files to a target in CMake if the target is an executable or a library with the following command:

add_executable(${target_name} ${source_files})

或 add_library（$ {target_name} $ {source_files}）

然后我的问题是，如果目标不是可执行文件或库，该怎么办？之所以提出这个问题，是因为我想用Doxygen建立文档的目标，并且可以使用以下命令来完成：

Then my question is what if the target is not an an executable or a library. I raise this question because I want to build a target for documentation with Doxygen, and this can be done with the following commands:

find_package(Doxygen)
if(DOXYGEN_FOUND)
  set(doxyfile_in  ${CMAKE_CURRENT_SOURCE_DIR}/Doxyfile.in) #doxygen file
  set(doxyfile    ${PROJECT_BINARY_DIR}/Doxyfile)
  #configure the doxygen file
  configure_file(${CMAKE_CURRENT_SOURCE_DIR}/Doxygen.in ${PROJECT_BINARY_DIR}/Doxyfile @ONLY)
  add_custom_target( doc ALL
    COMMAND ${DOXYGEN_EXECUTABLE} ${doxyfile}
    WORKING_DIRECTORY ${PROJECT_BINARY_DIR}
    COMMENT "Generating API documentation with Doxygen" VERBATIM
  )
endif(DOXYGEN_FOUND)

使用Visual Studio， doc 成为目标，我也想添加 Doxyfile.in 项目中的文件，以防万一我需要在IDE中更改一些变量。关于如何在 doc 目标上添加此文件的任何想法？谢谢。

With Visual Studio, doc becomes a target, and I also want to add Doxyfile.in file in the project just in case that I need to change some variables inside with the IDE. Any ideas on how I can add this file on the doc target? Thanks.

推荐答案

您可以使用SOURCES 参数http://www.cmake.org/cmake/help/v2.8.12/cmake.html#command%3aadd_custom_target rel = nofollow title = CMake文档 add_custom_target命令> add_custom_target ：

You can use the SOURCES argument of add_custom_target for this:

add_custom_target( doc ALL
  COMMAND ${DOXYGEN_EXECUTABLE} ${doxyfile}
  WORKING_DIRECTORY ${PROJECT_BINARY_DIR}
  COMMENT "Generating API documentation with Doxygen" VERBATIM
  SOURCES ${CMAKE_CURRENT_SOURCE_DIR}/Doxygen.in
)
