Error near the end of compling using WinBuilder any TIPS?

Hi, I got this error near the end of compling using WinBuilder any TIPS?

pcbnew\github\CMakeFiles\openssl.dir\build.make:88: recipe for target ‘G:/KiCad/wbldr342/src/kicad/.downloads-by-cmake/openssl-1.0.1e/src/openssl-stamp/openssl-download’ failed
CMakeFiles\Makefile2:1566: recipe for target ‘pcbnew/github/CMakeFiles/openssl.dir/all’ failed
Makefile:115: recipe for target ‘all’ failed

Just did a clean build on C:\ and it worked. thanks.
