| # known to make use of "if (CMAKE_BUILD_TYPE MATCHES xxx)". |
| # If about to be set - needs to be set before invoking cmake_src_configure. |
| # |
| # The default is RelWithDebInfo as that is least likely to append undesirable |
| # flags. However, you may still need to sed CMake files or choose a different |
| # build type to achieve desirable results. |

| # In EAPI 7, the default was non-standard build type of Gentoo. |

| # for econf and is needed to pass TRY_RUN results when cross-compiling. |
| # Should be set by user in a per-package basis in /etc/portage/package.env. |

| # the ebuild. Helps in improving QA of build systems that write to source tree. |
