I'm trying to figure out how to ensure my build uses my internal version
of boost. My directory structure looks like:
./CMakeLists.txt
./mylib/CMakeLists.txt
./dependencies/boost/...
How do I structure my find_package to use the internal one?
Something like this ought to work, provided you rename your 'boost'
subfolder to something more specific (e.g., boost_1_44_0 or whatever):
set(CMAKE_PREFIX_PATH ${CMAKE_CURRENT_SOURCE_DIR}/dependencies)
find_package(Boost REQUIRED
COMPONENTS
thread system program_options date_time random)
I don't like setting CMAKE_PREFIX_PATH from CMakeLists.txt like this
because it prevents people from overriding it on the commandline, but it
may be just what you need. (There may be a 'better' variable to set that
has the same effect, I don't know.)
I'm not sure what the '-mt' suffix is for in your find_package() call,
though. This definitely didn't work for me until I removed the '-mt'
part from all the COMPONENTS. (I think you're supposed to set
Boost_USE_MULTITHREADED to control this, and it defaults to ON[?])
HTH...

I've tried this:
set(BOOST_ROOT "${DEPENDENCY_DIR}/boost")
find_package( Boost
COMPONENTS
thread-mt system-mt program_options-mt date_time-mt
random-mt
PATHS ${BOOST_ROOT}
)
But that gives me the following error:
CMake Error at dependencies/boost/tools/build/CMake/BoostConfig.cmake:98
(boost_report_pretty):
Unknown CMake command "boost_report_pretty".
Call Stack (most recent call first):
CMakeLists.txt:287 (find_package)
If I don't specify PATHS (even if I specify BOOST_ROOT), it uses the
boost I have installed on my system.
I can't find any documentation on how to actually use Boost.Cmake. :)
Help greatly appreciated.
