No, that's wrong in principle.
In the cmake files there is no current target, they describe all targets.
If you want to do something when some target is built, you have to do this via
dependencies, either via add_custom_command() or add_custom_target().
Hm, the reason I want it is because of how I am using CMake and
triggering a generator. I have to translate .e files (Euphoria) into .c
files when the source .e files change. Yesterday, Bill Hoffman helped me
quite a bit with this and I finally got that working. The only problem
is that we translate 3 main programs, the interpreter, the translator
and the backend. Each one produces about 115,000 lines of C code and it
takes ~20 seconds for each target. So, here's what happens... I edit
common.e which is included in all three programs (interpreter,
translator and backend). Right now I am working on the interpreter, so I do:
wmake eui
To rebuild the interpreter. However, CMake now sees that common.e has
changed, it triggers running cmake.exe to rebuild the makefiles and when
it does so, all three produces are triggered for a generation because
common.e has changed. That would be correct if I was building all three
programs, however, I am only working on the interpreter, I don't want to
wait an extra 40 seconds to translate the backend and translator when I
am not working on it. Now, wmake eui only compiles the interpreter
source files, but the translation is time consuming (considering you
edit, compile, edit compile, etc...).
Some how I would like to realize that they want to build the interpreter
only, don't worry about re-translating the translator and backend right now.
You can see my two main CMake files in :
http://rapideuphoria.svn.sourceforge.net/viewvc/rapideuphoria/trunk/source/
to see how I am doing this currently. I just can't figure out how to not
re-translate the other programs that I really don't care about right now.
Thanks for any help,
Jeremy
