Subject: CMake: Concatenate subsequent compiler flag strings with a space
X-Git-Tag: v9.0.0-rc1~1461^2~1
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7948cd0e1c7f50066c71a2641100eaa54f473db3;p=dealii.git

CMake: Concatenate subsequent compiler flag strings with a space

Otherwise compilation of a target that already has compile flags and is
set up with DEAL_II_SETUP_TARGET will fail.
