CMakeLists - Make linker do not find files

Question

I am trying to get running the GPIO_EXTI example from the STM32Cube_FW_F4_V1.24.0 using CMake and the actual GNU Tool Chain Version 9_2019_q4_major on Windows via Cygwin Terminal. The Project shall run on the STM32F4-DISCOVERY board.

I have a CMakeLists.txt file, which based on Cmake File.

cmake_minimum_required (VERSION 3.5)

project(F4cmake)

enable_language(C ASM)

I don't understand, why the linker says he has no input files.

In the CMakeLists.txt I explicitely added the linker (arm-none-eabi-ld.exe) because, if I do not add the linker, I got other failure and MAKE is using an other linker what I don't understand why.

I don't see my failure.

1. Can someone tell me what I am doing wrong?
2. Why is make using different linker?
3. How to fix the CMakeLists.txt file, so Make can generate an *.elf output file?

Thank you

I answer to my own question.

It is important, that all parameters for e.g. CMAKE_C_FLAGS are in one line, otherwise creating of the make file will fail.

The code of the toolchain cmake file is:

include(CMakeForceCompiler)

# set the CMake-identifier of the target paltform to build for
set (CMAKE_SYSTEM_NAME Generic)
# set the CMake-identifier of the target architecture to build for
set (CMAKE_SYSTEM_PROCESSOR arm)

# set linker flags. The only important settings are -T ${} and -Wl,--gc-sections otherwise creating of makefile will not work
