Subject: Use single command line arg for /FI (#869)
X-Git-Tag: v4.4~192
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=aa179512fc69bbcdc6e24a21491263c57ec98f57;p=thirdparty%2Fccache.git

Use single command line arg for /FI (#869)

CMake seems to interpret /FI and its argument as two separate options.
For instance, CMake de-duplicates arguments, leading any to non-first
/FI flag to be removed. This might be the reason why the option is not
honored with Visual Studio 16.10.2 / CMake 3.20.3.

Fix by combining /FI and its argument into a single command line option.
