CDK Build Break on RedHat9

[bf244a]

Hello,
I am trying to build the latest CDK on RedHat9, but I got the following error:
./configure: line 21174: syntax error near unexpected token 'DIRECTFB,'
./configure: line 21174: 'PKG_CHECK_MODULES(DIRECTFB,directfb>=$DIRECTFB_VERSION)'

Appreciate help.
Thank you.

Do you have pkg-config installed as advised in the prerequisites?

If yes, then try a "locate pkg.m4" and see if the directory it's in is the same as the one you get with "aclocal --print-ac-dir".

If not then copy it manually (have seen that happening but usually it was due to some manual un/reinstalls of the autotools) or try reinstalling pkg-config.

I made the manual copy, and the whole build went successful.
Thank you very much for your help.
