Re: [boost] [B2] Propagate CXX requirements to consumers

The problem is that you have <build>no and <build>yes at the same time on Windows. The conditional rule I suggested would produce no additional properties on Windows (so that the test builds, provided that it is not disabled by other requirements) and <build>no on other target systems.

rule check-windows ( properties * ) {     local result ;     if ! <target-os>windows in $(properties)     {         result = <build>no ;     }     return $(result) ; }

Got it now, thanks a lot. Working and CI is happy!
