使用cmake将源文件放入INSTALL目标中

Question

I asked a question How to add files to a non-executable or non-library target with CMake a few days ago, and the best solution to this problem is to use add_custom_target command.

However, this solution may not work if the target is created by CMAKE itself. For example, the INSTALL target that is created automatically when running CMAKE. Suppose, I also put some additional files under the INSTALL project, what should I do? I have tried the following command, but failed:

add_custom_target( INSTALL  
  SOURCES ${CMAKE_CURRENT_SOURCE_DIR}/file_to_be_added.h
)

Answer 1

CMake's default INSTALL target cannot be modified. You can however add a custom target, which does the same thing as the INSTALL target and has additional files added, eg:

add_custom_target(myinstall
    COMMAND "${CMAKE_COMMAND}" "-DBUILD_TYPE=$<CONFIGURATION>"
        "-P" "${CMAKE_BINARY_DIR}/cmake_install.cmake"
    SOURCES "${CMAKE_CURRENT_SOURCE_DIR}/file_to_be_added.h"
    WORKING_DIRECTORY "${CMAKE_BINARY_DIR}")
