This is a backport of the commits in PR 235 (“Fixes for packaging on
linux-like systems”), which was merged upstream:

https://github.com/opengribs/XyGrib/pull/235

It fixes finding resources such as icons, maps and translations installed in
the data directory.  This patch has been merged upstream and can be removed
with the next release.

Sightly adapted to find openjpg-2.4.

 ## Build and package
+### Options
 
+XyGrib has two CMake options
+- GNU_PACKAGE (DEFAULT: OFF)
+```
+Files will be installed in GNU standard installation directories such as prefix/bin and prefix/share.
+Packagers are recommended to test this option.
+```
+- GEN_TRANSLATION (DEFAULT: ON)
+```
+Create targets to generate translation files.
+Turning this off removes the need for qt-linguist, part of qttools-5 qt5 submodule, during build.
+```
