Build libfreetype with custom, embedded environment fails

Hi everybody,

I'm trying to build the original and official libfreetype for a embedded
platform (to be more accurate: a bare-metal application which is built with
the CodeComposerStudio by Texas Instruments). As libfreetype is ANSI-C
based, this should be no problem (unfortunately it is).

All the predefined build-struff like the cmake and other scripts/Makefiles
can not be used as they do not fit to the CCS environment, so I tried to
set it up from scratch. What I have done so far:

   -

   copied the freetype-2.10.0 folder into my working directory
   -

   in src/ I have removed all subdirectories except base, psnames, sfnt,
   truetype in order to get a minimalistic library which supports TTF only
   -

   the include/ directory was left untouched
   -

   in my project settings I have added a include-path which points to
   include/
   -

   in my project settings I have added a definition FT2_BUILD_LIBRARY in
   order to let it build a linkable library

Unfortunately something seems to be missing as I have a lot of undefined
stuff here:

   -

   FT_ERR_PREFIX is undefined in fterrors.c
   -

   FT_Error_String( FT_Error error_code ) in fterrors.h causes an error
   -

   FT_EXPORT in fterrors.h is undefined
   -

   the whole FT_NOERRORDEF_ stuff in fterrdef.h is undefined
   -

   when I ensure FT_ERR_PREFIX being defined for FT_NOERRORDEF_, it
   complains about all the errorcodes (such as Cannot_Open_Resource) not being
   defined in fterrdef.h

So it seems, something important is missing. Any hints/ideas what is wrong
here?

Thanks!

PS: this is the output of the compiler:
