[CMake] Correct Boost version found, linked against wrong one

[Florian Lindner]

Hello,

I have a simple cmake file for a small project. That project uses boost and links again a shared lib that also uses boost:

find_library(precice precice PATHS $ENV{PRECICE_ROOT}/build $ENV{PRECICE_ROOT}/build/last)
find_package(Boost 1.60.0 REQUIRED COMPONENTS system program_options filesystem)

add_executable(preciceMap src/preciceMap.cpp src/common.cpp)
target_include_directories(preciceMap PRIVATE ${Boost_INCLUDE_DIRS})
target_link_libraries(preciceMap ${Boost_LIBRARIES})
target_link_libraries(preciceMap ${precice})

output is:

CMake finds boost 1.66 but why does it try to link against 1.54.0? $BOOST_ROOT is set and $LIBRARY_PATH, $LD_LIBRARY_PATH and $CPLUS_INCLUDE_PATH are also set appropriately.

:~/software/aste/build> ls $BOOST_ROOT/lib/*filesystem*
/opt/hlrs/tools/boost/1.66.0/lib/libboost_filesystem.a  /opt/hlrs/tools/boost/1.66.0/lib/libboost_filesystem.so  /opt/hlrs/tools/boost/1.66.0/lib/libboost_filesystem.so.1.66.0

:~/software/aste/build> ls /usr/lib64/*filesystem*
/usr/lib64/libboost_filesystem-mt.so  /usr/lib64/libboost_filesystem.so  /usr/lib64/libboost_filesystem.so.1.54.0

Maybe it prefers the -mt variants? But how can I get it to link against the correct files, i.e., 1.66?

Or is the "DSO missing from command line" another problem? All I found about that is that boost_system should be added, but that's already the case.

cmake version is 3.5.2

Thanks,
Florian
