Отсюда только одна строка CMakeLists.txt в каталогах с дочерними каталогами, как в bsp/CMakeLists.txt, если только в них нет источников.

Так выглядит файл CMakeLists.txt в каталогах с исходными файлами.

Запуск CMake
Сборка вызывается с помощью следующих команд:
rm -rf build
mkdir -p build
cd build
cmake -D CMAKE_BUILD_TYPE=Debug \
-D CMAKE_TOOLCHAIN_FILE="arm-gcc-toolchain.cmake" \
-D CMAKE_C_FLAGS="-fdiagnostics-color=always" \
--verbose \
..
make

После этого файла Driver_CAN.c.obj в файле неткаталог CMakeFiles/kv11.dir/CMSIS/Driver/DriverTemplates.
Что не так с конфигурацией CMake, из-за которой не создаются промежуточные файлы .obj, из-за чего библиотека не связывается должным образом.
