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.

*** [Makefile:84: all] Error 2
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.
Can someone tell me what I am doing wrong?
Why is make using different linker?
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)
