# 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
