[FFmpeg-devel] configure error: pkg not found even though it is available

Hello,

I compile the static binaries for macOS and just got a configure error:

ERROR: libvmaf >= 2.0.0 not found using pkg-config

The file looks as follows:

$ cat libvmaf.pc
prefix=/Users/Shared/ffmpeg/sw
libdir=${prefix}/lib
includedir=${prefix}/include

Name: libvmaf
Description: VMAF, Video Multimethod Assessment Fusion
Version: 2.3.0
Libs: -L${libdir} -lvmaf -lm
Cflags: -I${includedir} -I${includedir}/libvmaf

And the library also exists in the lib directory.

The full config.log is here: https://evermeet.cx/pub/tmp/config.log

This commit broke it: 3d29724c00

Cheers,
  K. C.

Specific error is

     error: use of undeclared identifier 'vmaf_init'

The filter includes  <libvmaf.h>

Confirm that /Users/Shared/ffmpeg/sw/include/libvmaf  has current header 
which declares vmaf_init()

It builds here.

Yes, the header file exists in the directory and the function vmaf_init() is
declared.

The vmaf version commit hash is aa1dd0b3. I compiled this version right
before ffmpeg and all libvmaf files have the correct timestamp (todays).

I can only say that the compile run worked a few days ago.

Cheers,
  K. C.

P.S.: Heading to bed. Will be up in 5-6 hours.

Might there be a stale header in an cflags path with earlier precedence?

Argh, why haven't I thought of that. It was way too late for me yesterday
and apparently I couldn't think straight anymore.

Sorry for the noise. Yes, there was an old header file in the folder above.
Sometimes I wish that "make install" would take care of such things.

Once again, I am sorry.

Cheers,
 K. C.
