PKG_CONFIG_PATH
The
pkg-config
utility is a hard requirement for configuring and
building Mesa on Unix-like systems. It is used to search for external libraries
on the system. This environment variable is used to control the search path for
pkg-config
. For instance, setting
PKG_CONFIG_PATH=/usr/X11R6/lib/pkgconfig
will search for package
metadata in /usr/X11R6
before the standard directories.
One of the oddities of meson is that some options are different when passed to
the meson
than to meson configure
. These options are
