| 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> |
