| # 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 |
