currently my CMakeLists.txt looks basically like this:
file(GLOB sources *.cc)
add_executable(myprog ${sources})
One of these cc-files just contains:
const char* build_date() {return __DATE__;}
The obvious problem here is that this build-date doesn't change
because the object stays the same until I make a change to that
specific source file.
How can I tell cmake that I want this file to be rebuilt every
time I make a change to one of the other source files?
It sounds like you want to "See the OBJECT_DEPENDS option in
SET_SOURCE_FILES_PROPERTIES to add file-level dependencies to object
files." I.e. make the object of your build_date source depend on every
other source.
Setting OBJECT_DEPENDS is archaic. I doubt this is adviseable.
