Subject: CMake: simplify Target.config generation
X-Git-Tag: relicensing~773^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1bb794c7a0f979cf1f211a260504924ca056e7b2;p=dealii.git

CMake: simplify Target.config generation

Let us call the export(TARGETS ...) function at one central place. This
simplifies the configuration logic significantly and avoids accidentally
recreating the file.
