>Description:
I was attempting to build:
https://github.com/afwbkbc/glsmac

It uses CMAKE, but failed to find the (already installed) SDL2, while it did find SDL2_image.

Comparing the two, SDL2_image has a file:
/usr/pkg/lib/pkgconfig/SDL2_image.pc

While the corresponding file for SDL2 is:
/usr/pkg/lib/pkgconfig/sdl2.pc

I made a new file /usr/pkg/lib/pkgconfig/SDL2.pc by copying sdl2.pc into it. CMAKE detected it correctly.

It would appear this is a (n edge?) case of case-sensitivity, and the SDL2 package should be patched to capitalize SDL2.pc.
>How-To-Repeat:
Build any package that depends on SDL2, but especially:
https://github.com/afwbkbc/glsmac
>Fix:
It would appear this is a (n edge?) case of case-sensitivity, and the SDL2 package should be patched to capitalize SDL2.pc.

Patching the next release/revision would be the best solution.
