| 3 | # AX_LIB_CRYPTOPP([ACTION-IF-FOUND],[ACTION-IF-NOT-FOUND]) |
| 4 | # |
| 5 | # DESCRIPTION |
| 6 | # |
| 7 | # Test for the Crypto++ library |
| 8 | # |
| 9 | # If no intallation prefix to the installed Crypto++ library is given the |
| 10 | # macro searches under /usr, /usr/local, and /opt. |
| 11 | # |
| 12 | # This macro calls: |
| 13 | # |
| 14 | # AC_SUBST(CRYPTOPP_INCLUDES) |
| 15 | # AC_SUBST(CRYPTOPP_LDFLAGS) |
| 16 | # AC_SUBST(CRYPTOPP_LIBS) |
| 17 | # |
| 18 | # And sets: |
| 19 | # |
| 20 | # HAVE_CRYPTOPP |
