Subject: [PATCH] configure.ac: prefer pkg-config to find libgcrypt
|
||
|
|
|
||
|
|
libgcrypt from 1.8.5 provides a pkg-config file as well as the traditional
|
||
|
|
libgcrypt-config script. As pkg-config is more resiliant in the face of
|
||
|
|
complicated build environments (for example cross-compilation and sysroots)
|
||
|
|
prefer the pkg-config file, falling back to libgcrypt-config if that doesn't
|
||
|
|
exist.
