How to build a stm32 with cmake - c

Question

I want to build a stm32 project with cmake. The host is Linux ubuntu 4.4.0-98-generic.
This is my CMakeLists.txt script file. I wrote this file refer to my Makefile. The Makefile works well.
cmake_minimum_required (VERSION 3.5)
set (CMAKE_SYSTEM_NAME Generic)
set (CMAKE_SYSTEM_PROCESSOR arm)
set (CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR})
set (CMAKE_ASM_COMPILER arm-none-eabi-as)
set (CMAKE_C_COMPILER arm-none-eabi-gcc)
set (CMAKE_OBJCOPY arm-none-eabi-objcopy)
set (CMAKE_OBJDUMP arm-none-eabi-objdump)
set (CMAKE_SIZE arm-none-eabi-size)
set (TARGET hUart)
set (MCU stm32f401re)
set (BOARD stm32f401re-nucleo)
set (APP uart)
set (CMAKE_ASM_FLAGS
-mcpu=cortex-m4 -mthumb -mfloat-abi=hard -mfpu=fpv4-sp-d16
)
set (CMAKE_C_FLAGS
-mcpu=cortex-m4 -mthumb -mfloat-abi=hard -mfpu=fpv4-sp-d16
-fno-common -fsigned-char -fmessage-length=0
-Wall -Wextra -Wshadow
-Os -ffunction-sections -data-sections
-g3
-std=c11
)
set (CMAKE_EXE_LINKER_FLAGS
-spec=nosys.specs -spec=nano.specs -u _printf_float -u _scanf_float
-Wl,--gc-sections -Wl,-map=${TARGET}.map,--cref
)
add_definitions (
-DNDEBUG
-DSTM32F401xE -DUSE_HAL_DRIVER -DUSE_FULL_ASSERT
-DUSE_STM32F4XX_NUCLEO
)
project (${TARGET})
include_directories (
drivers/${MCU}/cmsis
drivers/${MCU}/hal
bsp/${BOARD}
projects/${BOARD}
apps/${APP}
)
file (GLOB STARTUP
drivers/${MCU}/startup/*.s
)
message (STATUS "[DBG]: ${STARTUP})
file (GLOB CMSIS_SRCS
drivers/${MCU}/cmsis/*.c
drivers/${MCU}/hal/*.c
)
file (GLOB BSP_SRCS
bsp/${BOARD}/*.c
)
file (GLOB APP_SRCS

apps/uart/*.c
)
message (STATUS "[DBG]: ${APP_SRCS})
set (LINKER_SCRIPT drivers/${MCU}/linker/STM32F401VEHx_FLASH.ld)
add_executable (${TARGET}.elf ${STARTUP} ${CMSIS_SRCS} ${BSP_SRCS} ${APP_SRCS} ${LINKER_SCRIPT})
add_custom_target (${TARGET}.bin

COMMAND ${CMAKE_OBJCOPY} -O binary ${TARGET}.elf ${TARGET}.bin
)
add_custom_target (${TARGET}.lst
DEPENDS ${TARGET}.elf
COMMAND ${CMAKE_OBJDUMP} -Sdh ${TARGET}.elf > ${TARGET}.lst
The error log like this.
ompiling the C compiler identification source file "CMakeCCompilerId.c" failed.

Now, how can I fix this?
And, how to create the dependencies? I can do it '-MM -MT' options on Makefile.
All other options are exactly same as Makefile.
