9 | # DESCRIPTION |
---|
10 | # |
---|
11 | # Look for xmlsec1 in a number of default spots, or in a user-selected |
---|
12 | # spot (via --with-xmlsec1). Sets |
---|
13 | # |
---|
14 | # XMLSEC1_INCLUDES to the include directives required |
---|
15 | # XMLSEC1_LIBS to the -l directives required |
---|
16 | # XMLSEC1_LDFLAGS to the -L or -R flags required |
---|
17 | # |
---|
18 | # and calls ACTION-IF-FOUND or ACTION-IF-NOT-FOUND appropriately |
---|
19 | # |
---|
20 | # This macro sets XMLSEC1_INCLUDES such that source files should use the |
---|
21 | # xml/ directory in include directives: |
---|
22 | # ... <xmlsec/xmlsec.h> |
---|
