| 1 | # - a pkg-config module for CMake |
|---|
| 2 | # |
|---|
| 3 | # Usage: |
|---|
| 4 | # pkg_check_modules(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*) |
|---|
| 5 | # checks for all the given modules |
|---|
| 6 | # |
|---|
| 7 | # pkg_search_module(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*) |
|---|
| 8 | # checks for given modules and uses the first working one |
|---|
| 9 | # |
|---|
| 10 | # When the 'REQUIRED' argument was set, macros will fail with an error |
|---|
| 11 | # when module(s) could not be found |
|---|
| 12 | # |
|---|
| 13 | # It sets the following variables: |
|---|
| 14 | # PKG_CONFIG_FOUND ... true iff pkg-config works on the system |
|---|
| 15 | # PKG_CONFIG_EXECUTABLE ... pathname of the pkg-config program |
|---|
| 16 | # <PREFIX>_FOUND ... set to 1 iff module(s) exist |
|---|
| 17 | # |
|---|
| 18 | # For the following variables two sets of values exist; first one is the |
|---|
| 19 | # common one and has the given PREFIX. The second set contains flags |
|---|
| 20 | # which are given out when pkgconfig was called with the '--static' |
|---|
| 21 | # option. |
|---|
| 22 | # <XPREFIX>_LIBRARIES ... only the libraries (w/o the '-l') |
|---|
| 23 | # <XPREFIX>_LIBRARY_DIRS ... the paths of the libraries (w/o the '-L') |
|---|
| 24 | # <XPREFIX>_LDFLAGS ... all required linker flags |
|---|
| 25 | # <XPREFIX>_LDFLAGS_OTHERS ... all other linker flags |
|---|
| 26 | # <XPREFIX>_INCLUDE_DIRS ... the '-I' preprocessor flags (w/o the '-I') |
|---|
| 27 | # <XPREFIX>_CFLAGS ... all required cflags |
|---|
| 28 | # <XPREFIX>_CFLAGS_OTHERS ... the other compiler flags |
|---|
| 29 | # |
|---|
| 30 | # <XPREFIX> = <PREFIX> for common case |
|---|
| 31 | # <XPREFIX> = <PREFIX>_STATIC for static linking |
|---|
| 32 | # |
|---|
| 33 | # There are some special variables whose prefix depends on the count |
|---|
| 34 | # of given modules. When there is only one module, <PREFIX> stays |
|---|
| 35 | # unchanged. When there are multiple modules, the prefix will be |
|---|
| 36 | # changed to <PREFIX>_<MODNAME>: |
|---|
| 37 | # <XPREFIX>_VERSION ... version of the module |
|---|
| 38 | # <XPREFIX>_PREFIX ... prefix-directory of the module |
|---|
| 39 | # <XPREFIX>_INCLUDEDIR ... include-dir of the module |
|---|
| 40 | # <XPREFIX>_LIBDIR ... lib-dir of the module |
|---|
| 41 | # |
|---|
| 42 | # <XPREFIX> = <PREFIX> when |MODULES| == 1, else |
|---|
| 43 | # <XPREFIX> = <PREFIX>_<MODNAME> |
|---|
| 44 | # |
|---|
| 45 | # A <MODULE> parameter can have the following formats: |
|---|
| 46 | # {MODNAME} ... matches any version |
|---|
| 47 | # {MODNAME}>={VERSION} ... at least version <VERSION> is required |
|---|
| 48 | # {MODNAME}={VERSION} ... exactly version <VERSION> is required |
|---|
| 49 | # {MODNAME}<={VERSION} ... modules must not be newer than <VERSION> |
|---|
| 50 | # |
|---|
| 51 | # Examples |
|---|
| 52 | # pkg_check_modules (GLIB2 glib-2.0) |
|---|
| 53 | # |
|---|
| 54 | # pkg_check_modules (GLIB2 glib-2.0>=2.10) |
|---|
| 55 | # requires at least version 2.10 of glib2 and defines e.g. |
|---|
| 56 | # GLIB2_VERSION=2.10.3 |
|---|
| 57 | # |
|---|
| 58 | # pkg_check_modules (FOO glib-2.0>=2.10 gtk+-2.0) |
|---|
| 59 | # requires both glib2 and gtk2, and defines e.g. |
|---|
| 60 | # FOO_glib-2.0_VERSION=2.10.3 |
|---|
| 61 | # FOO_gtk+-2.0_VERSION=2.8.20 |
|---|
| 62 | # |
|---|
| 63 | # pkg_check_modules (XRENDER REQUIRED xrender) |
|---|
| 64 | # defines e.g.: |
|---|
| 65 | # XRENDER_LIBRARIES=Xrender;X11 |
|---|
| 66 | # XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp |
