[Pkg-cmake-team] Bug#732080: cmake: Boost is now multiarched

[Michael Banck]

Hi,

FWIW, I can reproduce the problem from one project I am packaging with
the following minimal CMakeLists.txt:

set(BOOST_ROOT ${BOOST})
set(Boost_NO_SYSTEM_PATHS TRUE)
set(Boost_DETAILED_FAILURE_MSG TRUE)
find_package(Boost 1.48 COMPONENTS thread system )

Without the patch:

mbanck at lightning:/tmp/cmake-boost-test/build$ cmake .. -DBOOST=/usr
-- The C compiler identification is GNU 4.9.2
-- The CXX compiler identification is GNU 4.9.2
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Could NOT find Boost
Boost version: 1.55.0
Boost include path: /usr/include
Could not find the following static Boost libraries:
        boost_thread
        boost_system
No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to
the directory containing Boost libraries or BOOST_ROOT to the location
of Boost.

And with:

mbanck at lightning:/tmp/cmake-boost-test/build$ cmake .. -DBOOST=/usr
-- The C compiler identification is GNU 4.9.2
-- The CXX compiler identification is GNU 4.9.2
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Boost version: 1.55.0
-- Found the following Boost libraries:
--   thread
--   system

Not sure the way they setup BOOST_ROOT and Boost_NO_SYSTEM_PATHS TRUE is
kosher, but wanted to let you know that there's at least corner-cases
where this patch might help.
