Hi,<br>
<br>
how should cmake find your MY_LIB-directory?<br>
The simplest way, is to add the directory using
"add_subdirectory(MY_LIB_DIR ...)"<br>
<br>
If the MY_LIB-build directory is somewhere else, in a completely
different directory, you should think about your project structure.<br>

Thanks for the reply - but I think you might have misunderstood my
question.<br>
<br>
I want to setup CMake so that when I call Cmake like so (for MY_APP):<br>
mkdir build && cd build<br>
cmake .. -G Xcode<br>
<br>
that the cmake call will be able to 'know' that it needs MY_LIB, find
where the MY_LIB CMakeLists.txt file is, build it, and then continue
with the cmake call for MY_APP.<br>
<br>
Any ideas?<br>
<br>

>From your description I think all your build script needs to do is:<br>

Further, assuming your library also gets build with CMake, you probably
have an add_directory(../MY_LIB ../MY_LIB) in your main lists-file
(otherwise you should) and then the link_directories() command is not
needed. I created sort of a 'standard' machinery for building a list of
'sub-packages' using CMake. It's not well documented and probably still
has many issues, but I could mail it to you if you think it may help
you get started and if you're interested.<br>

Hi,<br>
<br>
I am new to CMake - and whilst I am immediately impressed with it's
relative ease of use - I have a 'noob' question, I'm sure!<br>
<br>
I have the following:<br>
A library called MY_LIB that builds with a cmake command (I have
created a nice CMakeLists.txt file)<br>
An application called MY_APP that builds a nice application - and even
links in MY_LIB using:<br>
link_directories("../MY_LIB")<br>
target_link_libraries(MY_APP MY_LIB)<br>
<br>
Now, first of all I know that I'm not supposed to use relative paths..
but we'll call a side issue.. (though I'd be happy to hear the correct
way of doing things!) - the real problem that I have is this:<br>
<br>
Give than MY_LIB is built using CMake and MY_APP is built using CMake..
how can I setup my build scripts so that I can call CMake once for
MY_APP, it'll realise that it needs MY_LIB, which hasn't yet been
built, invoke CMake for MY_LIB and then link itself with MY_APP?<br>
<br>
I ask because I use libraries heavily to organise my code (and reuse)
and would love to switch to CMake for all my building (XCode 4 has
forced my hand!) but I can't seem to figure this out.<br>
<br>
Please help a newcomer out - any help is greatly appreciated!<br>
<br>
Thanks,<br>
<br>
David<br>
