# OpenCV note: the file has been extracted from CMake 2.6.2 distribution. |
||||
# It is used to build OpenCV with CMake 2.4.x |
||||
# |
||||
|
||||
# - a pkg-config module for CMake |
||||
# |
||||
# Usage: |
||||
# pkg_check_modules(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*) |
||||
# checks for all the given modules |
||||
# |
||||
# pkg_search_module(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*) |
||||
# checks for given modules and uses the first working one |
||||
# |
||||
# When the 'REQUIRED' argument was set, macros will fail with an error |
||||
# when module(s) could not be found |
||||
# |
||||
# It sets the following variables: |
||||
# PKG_CONFIG_FOUND ... true if pkg-config works on the system |
||||
# PKG_CONFIG_EXECUTABLE ... pathname of the pkg-config program |
||||
# <PREFIX>_FOUND ... set to 1 if module(s) exist |
||||
# |
||||
# For the following variables two sets of values exist; first one is the |
||||
# common one and has the given PREFIX. The second set contains flags |
||||
# which are given out when pkgconfig was called with the '--static' |
||||
# option. |
||||
# <XPREFIX>_LIBRARIES ... only the libraries (w/o the '-l') |
||||
# <XPREFIX>_LIBRARY_DIRS ... the paths of the libraries (w/o the '-L') |
||||
# <XPREFIX>_LDFLAGS ... all required linker flags |
||||
# <XPREFIX>_LDFLAGS_OTHER ... all other linker flags |
||||
# <XPREFIX>_INCLUDE_DIRS ... the '-I' preprocessor flags (w/o the '-I') |
||||
# <XPREFIX>_CFLAGS ... all required cflags |
||||
# <XPREFIX>_CFLAGS_OTHER ... the other compiler flags |
||||
# |
||||
# <XPREFIX> = <PREFIX> for common case |
||||
# <XPREFIX> = <PREFIX>_STATIC for static linking |
||||
# |
||||
# There are some special variables whose prefix depends on the count |
||||
# of given modules. When there is only one module, <PREFIX> stays |
||||
# unchanged. When there are multiple modules, the prefix will be |
||||
# changed to <PREFIX>_<MODNAME>: |
||||
# <XPREFIX>_VERSION ... version of the module |
||||
# <XPREFIX>_PREFIX ... prefix-directory of the module |
||||
# <XPREFIX>_INCLUDEDIR ... include-dir of the module |
||||
# <XPREFIX>_LIBDIR ... lib-dir of the module |
||||
# |
||||
# <XPREFIX> = <PREFIX> when |MODULES| == 1, else |
||||
# <XPREFIX> = <PREFIX>_<MODNAME> |
||||
# |
||||
# A <MODULE> parameter can have the following formats: |
||||
# {MODNAME} ... matches any version |
||||
# {MODNAME}>={VERSION} ... at least version <VERSION> is required |
||||
# {MODNAME}={VERSION} ... exactly version <VERSION> is required |
||||
# {MODNAME}<={VERSION} ... modules must not be newer than <VERSION> |
||||
# |
||||
# Examples |
||||
# pkg_check_modules (GLIB2 glib-2.0) |
||||
# |
||||
# pkg_check_modules (GLIB2 glib-2.0>=2.10) |
||||
# requires at least version 2.10 of glib2 and defines e.g. |
||||
# GLIB2_VERSION=2.10.3 |
||||
# |
||||
# pkg_check_modules (FOO glib-2.0>=2.10 gtk+-2.0) |
||||
# requires both glib2 and gtk2, and defines e.g. |
||||
# FOO_glib-2.0_VERSION=2.10.3 |
||||
# FOO_gtk+-2.0_VERSION=2.8.20 |
||||
# |
||||
# pkg_check_modules (XRENDER REQUIRED xrender) |
||||
# defines e.g.: |
||||
# XRENDER_LIBRARIES=Xrender;X11 |
||||
# XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp |
||||
# |
||||
