[CMake] Generated .rc files silently ignored

[Mueller-Roemer, Johannes Sebastian]

Hej hej,

for some reason your mail was not delivered to me and I only stumbled upon it by chance in the archives (while trying to find out where another one of my mails to the list disappeared to).

In any case, yes, I am adding the .rc file to my add_library command. The issue I have is that if I use mylib.rc in add_library and have an add_custom_command(OUTPUT mylib.rc ...) nothing is created but no error message is produced either (i.e. silently ignored). I have to use ${CMAKE_CURRENT_BINARY_DIR}/mylib.rc explicitly. For most files (such as generated .cpp files) using a relative path just works, because relative paths used in add_custom_command are interpreted relative to ${CMAKE_CURRENT_BINARY_DIR}.

Original text:

Hej,

Some more information about how you setup things would be useful. For instance: you would need to add the filename of the generated .rc file to the executable/library for which it is generated: are you doing that?

In the application I currently work on, we have created a small function to wrap the generation of the .rc file. I just checked that we actually also build a full path. That actually makes sense, because the generated file is put in the ${CMAKE_CURRENT_BINARY_DIR} and *not* in the current source dir. In other words: we could never accomplish this with any type of 'relative' path anyway. Are you maybe also mixing up the *SOURCE_DIR and *BINARY_DIR?

Sincerely,
Jakob
