Subject: [trac1999] add new configure option --with-gtest-source=PATH (checkpoint)
X-Git-Tag: trac2351_base~97^2~7^2~2^2~8^2~4
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a430ea9289e56be4d0749d587d70d2f419154e79;p=thirdparty%2Fkea.git

[trac1999] add new configure option --with-gtest-source=PATH (checkpoint)

This is incomplete and not all tested.

Added --with-gtest-source=PATH for location of the googletest source.

Also tested old method (--with-gtest not source) with gtest 1.6.0.
