#117 'can not find -lcurl' or 'curl-config not found'

[Eric Hivon]

On some systems not supporting libcurl (which may require to compile cfitsio with the flag '--disable-curl'), the configuration of HEALPix may crash with error messages like

curl-config not found

and/or

can not find -lcurl

If this is the case, replace the current ${HEALPIX}/hpxconfig_functions.sh with the one found at
https://sourceforge.net/p/healpix/code/HEAD/tree/branches/branch_v370r1154/hpxconfig_functions.sh,
and restart the HEALPix configuration procedure
