Subject: CMake: Bugfix: Replace all "-" by "_" for some internal variable name
X-Git-Tag: v8.2.0-rc1~123^2~2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=413bdbb7b53a15d0ef4d2d981510932fe8fdd030;p=dealii.git

CMake: Bugfix: Replace all "-" by "_" for some internal variable name

ENABLE_IF_SUPPORTED incorrectly exported invalid (cpp) macro definitions
containing a dash "-". Fix this by replacing all dashes with underscores
"_".
