2 # This script manages external libraries
4 # Some methods are added to manage external packages:
5 # 'PrepareLib': Checks the existence of an external library, if it
6 # doesn't exist, calls the script user provided to download(if required)
7 # and build the source code of the external library or notify user to
9 # 'Download': Download package from specify URL
10 # 'UnpackAll': Unpack the package
11 # 'Configure': Execute specify script(configure, bootstrap etc)
12 # 'InstallHeadFile': Install head files
13 # 'InstallLib': Install library binaries(.so, .a etc)
15 # By default, assume the script for an exteranl library is:
16 # <src_dir>/extlibs/<libname>/SConscript
18 # Note: After the external library is built:
19 # Head files should be installed to <src_dir>/deps/<target_os>/include
20 # lib(e.g .so, .a) should be installed to <src_dir>/deps/<target_os>/lib/<arch>
