i am not sure what you mean. the warning that you posted last time,  
was added by me manually. the procedure is as follows:

cmake, as we configured it, first calls find-scripts that are part of  
the cmake distribution (see IncludePackages.cmake). There you also  
find the following line: INCLUDE(FindBoost)

on ubuntu it seemed that the FindBoost.cmake script, that is part of  
the cmake distribution return TRUE if any package of boost is  
installed. it returns true, also if e.g. the program options part of  
boost is not installed. therefore arndt added two additional findboost- 
scripts, which are called in the FindPackages.cmake (the stuff that we  
check manually). in the two scripts, he added some extra code to make  
sure that not only boost is available, but that the two libs that yars  
needs of boost are there. currently i removed these two scripts from  
the list, because they are os-specific. once the mac port is  
completed, i will add them again. but that has nothing to do with the  
problem that you stated.

the Boost_INCLUDE_DIR is not provided by us. all variables that we  
define are uppercase all the way. to be honest, i dont remember what  
the FindBoost.cmake script does with the Boost_INCLUDE_DIR variable.  
you might want to look into that script, if the solutions below dont  
help.

you might try fink, but as i mentioned, i have not tried the fink  
installation myself, so i wont be able to help. on the other hand, it  
might work better with the FindBoost.cmake script.

so then a solution to your problem should be quite easy to find. see  
below.

true. but just make sure that the libraries in the external boost  
install directory are named:
e.g. libboost_program_options-mt-1_35.dylib. if they are named  
slightly different, then modify the modules/apple/SetLinkOptions.cmake  
script.

while looking for my boost installation, i saw that i did run the make  
install of boost, configuring it to install the libs and includes into  
my local external-lib directory. let me give some more details about  
that:

in my case, i have a place on the HD where i download and compile  
external libs, such as ode and boost. for each i configure them to  
install the files into another local directory. with automake this is  
done by:
./configure --prefix=/Users/home/somedir. this has one major advantage:

usually external packages will then ALL have the directory structure / 
Users/home/somedir/lib/ and /Users/home/somedir/include, so it  
suffices configure one prefix in the cmake script, i.e.  
YARS_EXTERNAL_PACKAGES_PREFIX, and then cmake/make will happily find  
all the files in YARS_EX.../include and YARS_EX../lib

in my case, Boost_INCLUDE_DIR points to /Users/home/somedir.

hope that helps.

cheers,
keyan
