Installing GSL library with CodeBlocks on Win10

I try to install GSL on Win10 with the the CodeBlocks IDE.
I downloaded the Complete package, except sources of 11 July 2006, from http://gnuwin32.sourceforge.net/packages/gsl.htm
I try a simple example with the following code

#include <stdio.h>
#include <stdlib.h>`
#include <gsl/gsl_sf_bessel.h>

int main(int argc, char* argv[])
{
    printf("Hello world!\n");
    double x = 5.0;
    double y = gsl_sf_bessel_J0(x);

    printf ("Besel test J0(%g) = %.18e\n", x, y);
    return 0;
}

I put the search directory for the compiler D:\Windows\Sofwares\gsl-1.8\include
and D:\Windows\Sofwares\gsl-1.8\lib\libgsl.a
D:\Windows\Sofwares\gsl-1.8\lib\libgslcblas.a
in the linker settings.

When I try to buid, I get the error message undefined reference to `gsl_sf_bessel_J0'|

The method I describe below is defined as "implicit linking of a dynamic library" (dll).
Step 1) Go to 'Project buid options' -> select 'Search directory' tab -> select 'Compiler' tab -> click on 'Add' button and browse for the GnuWin32\include folder.

Step 2) Stay on the 'search directories' tab and select 'linker' -> click on 'Add' button and browse for the GnuWin32\lib folder.

Step 3) Click on 'Linker settings' tab -> click on Add button and type the names of library files you need for using GSL.
The library files must be written without the 'lib' prefix and without the '.a' suffix.

Step 4) Go to the GnuWin32\bin directory -> copy the dll files (libgsl.dll and libgslcblas.dll) and paste to the folder containing your CodeBlock project file.

Paste the two dll files again into the bin/Debug and bin/Release directories, where you will find the executable file of your program.

Step 5) Write your own program, compile and start.
Now everything should work

I tested the program on an old version of Windows, but the procedure is the same.
