xf86-ati build errors after 'require libdrm 2.4.51' patch

[gradinaruvasile]

So. After the "require libdrm 2.4.51" patch, i am unable to build xf86-video-ati from git (i can if i revert that patch).
I have Debian Testing which ships libdrm 2.4.51 and i even built drm from git myself today (2.4.52), but i still get

Requested 'libdrm >= 2.4.51' but version of libdrm is 2.4.46

when i configure. I recloned both drm and xf86-video-ati so thats not a problem.

How can i find out which library/file is the culprit (maybe i have some stray files from previous builds?)? What is the mechanism of determining the installed library version?

cat /usr/lib{,32,64}/pkgconfig/libdrm.pc | grep Version:

this should list two times the same version and it should be larger than 2.4.51. If this is not the case then you are either missing a separate development package for libdrm or you didn't install it correctly when building it on your own.

Ok thanks. Turns out i had /usr/local/lib/pkgconfig/libdrm.pc which had the old version, surely from an older compilation - since then i moved to use the /usr/lib/x86_64-linux-gnu/ directory so that file remained in local and that is the first place to look for pkgconfig.
