Copy file from source directory to binary directory using CMake

Question

I\'m trying to create a simple project on CLion. It uses CMake (I\'m new here) to generate Makefiles to build project (or some sort of it)

All I need to is transfer

Answer 1

The suggested configure_file is probably the easiest solution. However, it will not rerun the copy command to if you manually deleted the file from the build directory. To also handle this case, the following works for me:

add_custom_target(copy-test-makefile ALL DEPENDS ${CMAKE_CURRENT_BINARY_DIR}/input.txt)
add_custom_command(OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/input.txt
                   COMMAND ${CMAKE_COMMAND} -E copy ${CMAKE_CURRENT_SOURCE_DIR}/input.txt
                                                    ${CMAKE_CURRENT_BINARY_DIR}/input.txt
                   DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/input.txt)
