Subject: [PATCH] Enhanced require_pkg_config() in configure to fallback to
require() if pkg-config is missing
Purpose: Enhanced require_pkg_config() in configure to
fallback to require() if pkg-config is missing
Notes: This is likely mainly of relevance when building with MSVC on
Windows. In my case, I used this approach to get libmfx when invoking
configure with --enable-libmfx, which is used for QuickSync (QSV).
Comments:
-- configure: Enhanced require_pkg_config() function to first check if
$pkg_config is not false. If not false, it goes through the
standard steps of calling use_pkg_config(), but if false, it issues
a log message and then calls require() with all the inputted
arguments and an additional argument: -l$1. So, for something like
"require_pkg_config libmfx "mfx/mfxvideo.h" MFXInit", this becomes
"require libmfx "mfx/mfxvideo.h" MFXInit -llibmfx". This is not a
perfect solution, but the previous approach didn't work at all
before when require_pkg_config() is used.
