CMake: Как добавить подкаталог с библиотекой?

0 голосов
/ 20 февраля 2019

Я не могу заставить cmake искать библиотеку в подкаталоге /usr/local/lib/db5.

Для поиска библиотек я использую следующий скрипт: 

link_directories(/usr/local/lib/db5 /usr/local/lib /usr/lib)

set (LIBRARIES
        c m util ssl pthread db)

foreach (LIBRARY ${LIBRARIES})
    find_library ("${LIBRARY}_FOUND" ${LIBRARY})
    message (STATUS "Check the ${LIBRARY} is installed: " ${${LIBRARY}_FOUND})
    if ( "${${LIBRARY}_FOUND}" STREQUAL "${LIBRARY}_FOUND-NOTFOUND" )
        message (STATUS "Adding library sources")
        add_subdirectory (../${LIBRARY} lib/${LIBRARY})
    endif ()
endforeach ()

Библиотекаопределенно присутствует в каталоге. 

ogogon@:/usr/local/src/util# ls /usr/local/lib/db5
libdb_cxx-5.3.a     libdb_cxx-5.3.so.0.0.0  libdb_cxx.so        libdb_stl-5.3.so.0  libdb_stl.a     libdb-5.3.so        libdb-5.so
libdb_cxx-5.3.so    libdb_cxx-5.so      libdb_stl-5.3.a     libdb_stl-5.3.so.0.0.0  libdb_stl.so        libdb-5.3.so.0      libdb.a
libdb_cxx-5.3.so.0  libdb_cxx.a     libdb_stl-5.3.so    libdb_stl-5.so      libdb-5.3.a     libdb-5.3.so.0.0.0  libdb.so

Поиск в библиотеке не приводит к успеху.

Если я удаляю библиотеку db из списка - все идет хорошо.

Что я делаю не так?Как мне решить эту проблему?

Теперь я решил эту проблему следующим образом: 

set (LIBPATHS /usr/local/lib/db5 /usr/local/lib /usr/lib libs5)

set (LIBRARIES
        c m util db ssl pthread)

foreach (LIBRARY ${LIBRARIES})
    find_library ("${LIBRARY}_FOUND" ${LIBRARY} PATHS ${LIBPATHS})
    message (STATUS "Check the ${LIBRARY} is installed: " ${${LIBRARY}_FOUND})
    if ( "${${LIBRARY}_FOUND}" STREQUAL "${LIBRARY}_FOUND-NOTFOUND" )
        message (STATUS "Adding library sources")
        add_subdirectory (../${LIBRARY} lib/${LIBRARY})
    endif ()
endforeach ()

Но, если версия библиотеки Berkley DB изменится, пути придется скорректировать.Есть ли способ написать что-то вроде / usr / local / lib / db *?
