using CMake add_custom_command, we cannot automatically find the output files. the script generate many cpp/h files but it is base on some templates. Of course the template change from time to time.

so we have:

set(THE_SCRIPT "/x/y/z/theScript")
set(GENERATED_FILES "file1.cpp" "file1.h" "file2.cpp" "file2.hpp" ...)
set (TPL_FILE "Template.ert")

add_custom_command(
   OUTPUT   ${GENERATED_FILES}
   COMMAND  ${THE_SCRIPT} -t ${TPL_FILE} -D ${CMAKE_CURRENT_BINARY_DIR}
   MAIN_DEPENDENCY ${TPL_FILE}
   DEPENDS  ${GENERATED_FILES}
)
target_sources(myTarget PRIVATE ${GENERATED_FILES})

The GENERATED_FILES variable is made by the developer each time he/she changes the template file. the dev runs the command, grab all the files created and update the variable.

I was trying to think of a way to use file(GLOB GENERATED_FILES ...)
to get the list of files. But I am not sure how to go about it!

  • `file(GLOB)` cannot find files which are not created yet. You really need to collect a list of generated files either manually or through a script running via `execute_process`. See [duplicate question](https://stackoverflow.com/questions/44076307/cmake-globbing-generated-files) for possible ways. – Tsyvarev Dec 21 '22 at 21:24
