16 dnl MINIMUN-VERSION is a string with the version number optionalliy prefixed | |
17 dnl with the API version to also check the API compatibility. Example: | |
18 dnl a MINIMUN-VERSION of 1:1.2.5 won't pass the test unless the installed | |
19 dnl version of libgcrypt is at least 1.2.5 *and* the API number is 1. Using | |
20 dnl this features allows to prevent build against newer versions of libgcrypt | |
