5 # SYNOPSIS
6 #
7 # AX_PATH_GENERIC(LIBRARY,[MINIMUM-VERSION,[SED-EXPR-EXTRACTOR]],[ACTION-IF-FOUND],[ACTION-IF-NOT-FOUND],[CONFIG-SCRIPTS],[CFLAGS-ARG],[LIBS-ARG])
8 #
9 # DESCRIPTION
10 #
11 # Runs the LIBRARY-config script and defines LIBRARY_CFLAGS and
12 # LIBRARY_LIBS unless the user had predefined them in the environment.
13 #
14 # The script must support `--cflags' and `--libs' args. If MINIMUM-VERSION
15 # is specified, the script must also support the `--version' arg. If the
16 # `--with-library-[exec-]prefix' arguments to ./configure are given, it
17 # must also support `--prefix' and `--exec-prefix'. Prefereable use
18 # CONFIG-SCRIPTS as config script, CFLAGS-ARG instead of `--cflags` and
19 # LIBS-ARG instead of `--libs`, if given.
20 #
21 # The SED-EXPR-EXTRACTOR parameter representes the expression used in sed
22 # to extract the version number. Use it if your 'foo-config --version'
23 # dumps something like 'Foo library v1.0.0 (alfa)' instead of '1.0.0'.
24 #
25 # The macro respects LIBRARY_CONFIG, LIBRARY_CFLAGS and LIBRARY_LIBS
26 # variables. If the first one is defined, it specifies the name of the
27 # config script to use. If the latter two are defined, the script is not
28 # ran at all and their values are used instead (if only one of them is
29 # defined, the empty value of the remaining one is still used).
30 #
31 # Example:
32 #
33 # AX_PATH_GENERIC(Foo, 1.0.0)
34 #
35 # would run `foo-config --version' and check that it is at least 1.0.0, if
36 # successful the following variables would be defined and substituted:
37 #
38 # FOO_CFLAGS to `foo-config --cflags`
39 # FOO_LIBS to `foo-config --libs`
40 #
41 # Example:
42 #
43 # AX_PATH_GENERIC([Bar],,,[
44 # AC_MSG_ERROR([Cannot find Bar library])
45 # ])
46 #
47 # would check for bar-config program, defining and substituting the
48 # following variables:
49 #
50 # BAR_CFLAGS to `bar-config --cflags`
51 # BAR_LIBS to `bar-config --libs`
52 #
53 # Example:
54 #
55 # ./configure BAZ_LIBS=/usr/lib/libbaz.a
56 #
57 # would link with a static version of baz library even if `baz-config
58 # --libs` returns just "-lbaz" that would normally result in using the
59 # shared library.
60 #
61 # This macro is a rearranged version of AC_PATH_GENERIC from Angus Lees.
