Subject: Cmake build: No need to recreate lyx.pot on every make call.
X-Git-Tag: 2.2.0alpha1~1611
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;ds=sidebyside;h=61f0634abf16937443f72d1d1faa0bd7558233c0;p=features.git

Cmake build: No need to recreate lyx.pot on every make call.

We can check if imput data for 'gettext' command has changed from previous call.
If not, there is no need to recreate lyx.pot, which we only differ in
	"POT-Creation-Date: ...."
