UsePkgConfig
|
|
------------
|
|
|
|
Obsolete pkg-config module for CMake, use FindPkgConfig instead.
|
|
|
|
|
|
|
|
This module defines the following macro:
|
|
|
|
PKGCONFIG(package includedir libdir linkflags cflags)
|
|
|
|
Calling PKGCONFIG will fill the desired information into the 4 given
|
|
arguments, e.g. PKGCONFIG(libart-2.0 LIBART_INCLUDE_DIR
|
|
LIBART_LINK_DIR LIBART_LINK_FLAGS LIBART_CFLAGS) if pkg-config was NOT
|
|
found or the specified software package doesn't exist, the variable
|
|
will be empty when the function returns, otherwise they will contain
|
|
the respective information
|
|
