Subject: build: Restore the ability to build gettext-tools separately, part 2.
X-Git-Tag: v0.20.2~68
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=37af7d71252a3967b4f98a4a9ed3477ea50d40a2;p=thirdparty%2Fgettext.git

build: Restore the ability to build gettext-tools separately, part 2.

* gettext-tools/configure.ac: New option --with-installed-csharp-dll.
(USE_INSTALLED_CSHARP_DLL): New conditional.
* gettext-tools/src/Makefile.am (CSHARP_DLL_DIR): New variable.
(msgunfmt.net.exe): Use it.
* configure.ac: Filter out --with-installed-csharp-dll from inherited --help
output.
* PACKAGING: Document that gettext-tools's configure needs to be invoked with
--with-installed-csharp-dll.
