Prefer finding an dnl external hwloc, build our internal one if required. If we can dnl not find an external hwloc and the internal one fails to dnl configure, abort. dnl dnl This macro will change the environment in the following way: dnl dnl * opal_hwloc_header [legacy] - will be set if building dnl internally, to the header file that should be included for dnl embedded builds. This is used by PRRTE, but should not dnl be used by new code. dnl * opal_hwloc_mode - either external or internal. If internal, dnl --with-hwloc should be ignored by other packages dnl * opal_hwloc_CPPFLAGS - the C Preprocessor flags necessary to dnl run the preprocessor on a file which relies on Hwloc dnl headers. This will be folded into the global CPPFLAGS, dnl so most people should never need this. dnl * opal_hwloc_LDFLAGS - the linker flags necessary to run the dnl linker on a file which relies on Hwloc libraries. This dnl will be folded into the global CPPFLAGS, so most people dnl should never need this. dnl * opal_hwloc_LIBS - the libraries necessary to link source which dnl uses Hwloc. Cannot be added to LIBS yet, because then dnl other execution tests later in configure (there are sadly dnl some) would fail if the path in LDFLAGS was not added to dnl LD_LIBRARY_PATH. dnl * CPPFLAGS, LDFLAGS - Updated opal_hwloc_CPPFLAGS and dnl opal_hwloc_LDFLAGS.
