Subject: configure.ac: pass kernel source path
X-Git-Tag: glsdk-6_00_00_07~28
X-Git-Url: https://git.ti.com/gitweb?p=glsdk%2Fomapdrmtest.git;a=commitdiff_plain;h=2996d8788a6de12b1bfc1bf8d31231b603f61630

configure.ac: pass kernel source path

By default the configure.ac only checked for videodev2.h in
/usr/src/linux-headers-$kversion.

With this patch the user can pass the kernel source path with the parameter
--with-kernel-source.
