Review request for Extra Cmake Modules and KDE Frameworks.


Repository: extra-cmake-modules


Description
-------

When the RELATIVE parameter in ECMGenerateHeaders is empty or not set, the _actualheader variable would be defined to "/cmake/current/source/dir//lowercaseclassname.h". 

The double slash breaks RPM's debug symbols extraction, because it canonicalizes the path, so it's shortened by one "/". The shortening is done to avoid double-slash in the beginning of the path, which is non-POSIX. However from my understanding it's not possible to truncate the size of directory table by 1 byte, so the debugedit utility aborts and the entire rpmbuild fails. See a relevant bug report with further information: https://bugzilla.redhat.com/show_bug.cgi?id=304121 (comment #2)

This patch simply makes sure that EGH_RELATIVE is either empty, or non-empty and terminated with slash.

With this patch we are able to build solid and kdnssd frameworks with RPM build tools.

Thanks,
