By default, configure will automatically choose the first valid value it finds
for each option. You can set it to interactive to find all possible values and
give you a choice:
''' + font.blue( 'make config interactive=1' ) + '''
If you have multiple compilers, we suggest specifying your desired compiler by
setting CXX, as the automated search may prefer a different compiler.
For options, see the `INSTALL.md` file.
Configure assumes environment variables CPATH, LIBRARY_PATH, and LD_LIBRARY_PATH
are set so your compiler can find libraries. See INSTALL.md for more details.
