Dear All, I'm trying to do something that may be very easy to implement, but I'm really struggling with it at the moment...
I have a project in which I generate various files in subdirectories. Which I
add to the main project file using add_subdirectory(...). Some of these files I
need to merge into a single file at the end of the build. For which I tried to
set up a custom command in my main project file. But I can't convince this main
project file to find out how to generate the files whose generation rule sits
in a subdirectory.
Attached is a simple example of what I mean. In this example it is possible to
execute the following commands successfully:
make SubdirTarget
make
Since by the time the main target is built, its source files are already
available. But if I try to just execute "make" first, I get:
Scanning dependencies of target MergeFiles
make[2]: *** No rule to make target `subdir/file3.txt', needed by `merged.txt'.
Stop.
make[1]: *** [CMakeFiles/MergeFiles.dir/all] Error 2
make: *** [all] Error 2
I tried a number of different directory/file name combinations by now, but the
problematic thing in the end seems to be that these files are generated in a
different directory than where I try to use them.
Do you have a suggestion on how I could do something like this?
Cheers,
Attila
