Continuing my work to switch my build chain to cmake for apr, apr-util and
httpd I now found the same problem in the optional components of apr-util
that was just fixed in httpd in r1543149: some defines are not quoted
correctly to the resource compiler when invoked from Visual Studio project
Can somebody apply the attached patch to apr-util 1.5.x?
(DEFINE_WITH_BLANKS): New macro.
apr_ldap): Use DEFINE_WITH_BLANKS to properly generate Visual Studio
2005-2013 project files.
DEFINE_WITH_BLANKS was copied from trawick's patch on httpd.
