bootstrap: Fix running multiple times in-source
Since !691 (merged) we include cmConfigure.h
via ""
instead of <>
.
This breaks the bootstrap
script when run more than once in an
in-source build. In that case cmConfigure.h
is generated next
to the source files that include it, so ""
-style includes prevent the
Bootstrap.cmk/cmConfigure.h
file from being included during bootstrap.
Fix this by teaching the bootstrap script to remove any cmConfigure.h
that may have been generated by an earlier run in an in-source build.
Fixes: #17082 (closed)
