Why do I get the error "fatal error: core_cm4.h: No such file or directory" when using the STM32F4 Discovery board or ARM Cortex M?

Why do I get the following error when trying to build the stm32f4discovery_gettingstarted example?

In file included from <command-line>:0:0:

C:/MATLAB/SupportPackages/R2015b/STM32F4-Discovery_FW_V1.1.0/Libraries/CMSIS/ST/STM32F4xx/Include/stm32f4xx.h:245:81: fatal error: core_cm4.h: No such file or directory

#include "core_cm4.h" /* Cortex-M4 processor and core peripherals */

compilation terminated.

gmake: * [stm32f4discovery_gettingstarted.o] Error 1

Make sure the following are true:

(1) The version of CMSIS is correct (4.3.0)

(2) The folder for CMSIS contains all of the following contents: the folder CMSIS, the folder Device, and the file ARM.CMSIS.pdsc

(3) The folder for CMSIS is specified correctly in the targetupdater

Hello, you need download cmsis packages from ARM github page[1] and must be copy to "C:\ProgramData\MATLAB\SupportPackages\R2017a\3P.instrset\cmsis.instrset" folder. If that "cmsis.instrset" folder is not exist in 3P.instrset folder, create it and paste cmsis package after unzip. Your cmsis.instrset folder will looks like that https://prnt.sc/i1ce3x . After you can compile your program without errors.

I have the same problem with 2017b. And I noticed that the generated mk file does not contain fill path to the CMSIS headers root, it contains -I/CMSIS/Include rather than having a full path like -Ic:/path/to/CMSIS/Include. The missing header file is under CMSIS/Include and the project doesn't compile.

Okay I can go to stm32f4discovery_gettingstarted_ert_rtw and edit stm32f4discovery_gettingstarted.mk file which also contains wrong path to /CMSIS/Lib/GCC/libarm_cortexM4lf_math.a and /CMSIS/RTOS/RTX/LIB/GCC/libRTX_CM4.a (paths aren't full too) and fix it all and then the project compiles. But next time I rebuild the project in Simulink it rewrites the makefile and the problem comes back. I did what murat said and it didn't help. It looks like I haven't done some CMSIS configuration step. Or the Simulink solution is wrong.
