Re: [CMake] Boost_DIR

When I do this: FIND_PACKAGE(Boost 1.51 COMPONENTS program_options required) I see a variable Boost_DIR that gets set to Boost_DIR-NOTFOUND, even though Boost_INCLUDE_DIR, Boost_LIBRARY_DIRS, and a whole bunch of other variables are set correctly, and the project builds correctly. Is there something else you have to do to get Boost_DIR to not say NOTFOUND?

Re: [CMake] Boost_DIR
I might be wrong but my understanding is that it's the other way arround: you provide Boost_DIR (root of your boost installation) and it finds the rest itself. I've been using it like that. I have a custom build of boost in a specific directory and an environnement variable Boost_DIR set to it. I also set Boost_ROOT to be sure because previous versions of CMake would look for it.

Joel Lamotte Joel, I tried that - with export Boost_DIR=/home/doriad/build/Boost_1_51/ in my ~/.profile and using: FIND_PACKAGE(Boost 1.51) ccmake still shows: Boost_DIR =*Boost_DIR-NOTFOUND But as I mentioned, Boost_INCLUDE_DIR and Boost_LIBRARY_DIRS are set correctly, and everything builds fine. It is just terribly confusing for one of the first things a user sees in ccmake is Boost_DIR-NOTFOUND, even though everything is configured properly!

It must be find_package internally setting that since it never found a BoostConfig.cmake file. I agree that it's confusing, but there are several different ways to build/install boost out in the wild, and FindBoost tries to accommodate all of them, even the installations without any BoostConfig file. (In my view, it's unfortunate that there are quite so many different ways of installing boost.) It's just one of the things I think you get used to with building a CMake project that uses boost... Maybe the FindBoost maintainers will chime in here, too. Perhaps there's a way to mark the variable INTERNAL when it finds a boost that has no config file. If not, though, myabe you could just do a mark_as_advanced() on it so it gets hidden from the view of the users of your project.

[CMake] Boost_DIR
Hi, does anyone know what this Boost_DIR variable is from the findBoost.cmake module? And why it is never found? Everything works well, I use BOOST_ROOT to set the path to the Boost distribution, just curious.
