# - obsolete pkg-config module for CMake
|
|
#
|
|
# Defines the following macros:
|
|
#
|
|
# 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
|
