Need help changing a makefile to static linking

Hi all,

I'm having a hard time compiling a plugin (softhddevice) for the video disk recorder software (vdr). Unfortunately the last official version of the plugin was published back in 2013 and even worse it has to be compiled against ffmpeg. The last working version of ffmpeg was 2.8.x, patches should make it work with 3.5.x (if you can find them). It's definitely not working with ffmpeg 4.x
So my thought was to forget about all the trouble with different versions and compile the plugin against a static built and working version of ffmpeg.
That was the quickly found plan, but the implementation is more than difficult if you are not used to deal with makefiles.
I tried to copy parts of the makefile(s) of tvheadend (which btw does exactly what I have in mind) that simply adds the .a files to the linking command. But without success. I know that there's the possibility to tell pck-config to use static libraries, but I have no glue where exactly in the makefile I have to insert this command and how I can force pkg-config to search within the ffmpeg directory.
I hope someone can push me in the right direction.
Thanks in advance
Alex

NAME
dlerror - get diagnostic information SYNOPSIS
[flag ... ] file ... [library] ... DESCRIPTION
is one of a family of routines that give the user direct access to the dynamic linking facilities (using the option on the compiler or com- mand line). returns a null-terminated character string (with no trailing newline) that describes the last error that occurred during dynamic linking processing. If no dynamic linking errors have occurred since the last invocation of returns NULL. Thus, invoking second time, immediately following a prior invocation, results in NULL being returned. MULTITHREAD USAGE
This routine is thread-safe. WARNINGS
The messages returned by may reside in a static buffer that is overwritten on each call to Application code should not write to this buf- fer. Programs wishing to preserve an error message should make their own copies of that message. SEE ALSO
dlclose(3C), dlopen(3C), dlsym(3C). Texts and Tutorials: (See the option) (See manuals(5) for ordering information) dlerror(3C)
