- CMAKE_BUILD_TYPE=Release will force -O3 instead of respecting our CFLAGS and CXXFLAGS - Theoretically, we could patch cmake to always use -O2 instead, however, patching will break users' expectation when compiling their our code. - RelWithDebInfo could be another option if it's acceptable to always have debug symbol available. - However, some projects ignore all CFLAGS and CXXFLAGS; - Some other projects relies on CMAKE_BUILD_TYPE=Release to install to correct location and/or disable coverage. - To get away with -O3, we need patching either ways, let's go with CMAKE_BUILD_TYPE=None, and patch all problematic softwares.
BUILD STYLES ============ These shell snippets provide support for multiple build systems, i.e GNU configure, CMake, etc. A build style file must provide at least the following functions: - do_configure - do_build - do_install If a source package defines its own do_xxx() function, the function defined in the build style file is simply ignored.
