nc: request thread support by default we need this for util::job::queue which is in pretty much everything, so we may as well globally enable threading. 2017-07-04 14:20:00 +10:00			`# Unconditionally link pthreads in. Some projects won't need it, but most`

cxx: only set GLIBCXX_DEBUG if using libstdc++ Some libraries detect the debug mode of the stdlib and try to integrate with the system headers (eg, range-v3) which obviously doesn't work well if we're using an alternative stdlib like clang's libc++. 2024-05-14 09:04:42 +10:00			`# cxx.cmake must be imported first`
Use CMAKE_CURRENT_LIST_DIR for local includes to simplify usage This means that we no longer need to modify the module path for CMake before including the root script. 2022-06-15 10:46:52 +10:00			`include ("${CMAKE_CURRENT_LIST_DIR}/nc_cxx.cmake")`
