How to change file permission when copying by add_custom_command in cmake
I am able to copy files by cmake using something like
file(GLOB IMAGES ${PROJECT_SOURCE_DIR}/Image/*)
file(COPY ${IMAGES} DESTINATION ${CMAKE_CURRENT_BINARY_DIR}/Image
FILE_PERMISSIONS OWNER_READ OWNER_WRITE GROUP_WRITE GROUP_READ WORLD_READ)
but the downside is this command will only be invoked when cmake is reconfigured. I figured out a way to copy them whenever a build is triggered like below
add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
COMMAND ${CMAKE_COMMAND} -E copy_directory
"${PROJECT_SOURCE_DIR}/Image"
"${CMAKE_CURRENT_BINARY_DIR}/Image")
this suits my needs by I am not able to figure out a way to alter the file permission like the first method. I need to alternate the file permission to make sure it is right otherwise some images might be wrongly classified as executable when running the below command
find . -executable -type f
Is it possible to alter the file permission when copying from add_custom_command?
