Subject: Cmake: Removed some useless empty SET statements.
X-Git-Tag: curl-7_38_0~57
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=06de7d69364c95ff1bb31c4999a32f3f1d9aed03;p=thirdparty%2Fcurl.git

Cmake: Removed some useless empty SET statements.

Undefined variables resolve to empty strings and we do not ever test if
the variable is defined thus those SETs are superfluous.
