CMake c CMAKE_SYSROOT не видит библиотеки в rootfs Выглядит это так:

библиотека librt-2.19.so и линк на нее librt.so.1 лежат в rootfs/lib/arm-linux-gnueabihf

Такое окружение используется на двух компах: на одном проект собирается, на другом возникают ошибки (выше) с библиотеками.
При перемещении системных библиотеки в локальную директорию библиотек проекта сборка происходит успешно.
Установка переменных CMAKE_LIBRARY_PATH и CMAKE_FIND_ROOT_PATH ничего не дает.
Чего не хватает на втором компе?
