freetype @2.10.4: fatal error: 'ft2build.h' file not found

[nsklaus (nsklaus)]

i'm trying to compile two projects: wine and dwm both suffer from the same problem, they have trouble locating freetype files.

here trying to compile dwm:

as for wine, i con configure and make it. no errors. freetype support is found during the ./configure. in the end when wine is built, i try to run it with: ./wine64 winecfg and there it complains it cannot find freetype support.. here's the output:

-> wine-6.1 $ ./wine64 notepad
Wine cannot find the FreeType font library.  To enable Wine to
use TrueType fonts please install a version of FreeType greater than
or equal to 2.0.5.

i'm on macos 11.2 rc, arm64 arch, but i run everything through rosetta2 (start term with rosetta2) so it's all x86_64 env.
