"""engine.SCons.Options.PathOption
|
|
|
|
This file defines an option type for SCons implementing 'package
|
|
activation'.
|
|
|
|
To be used whenever a 'package' may be enabled/disabled and the
|
|
package path may be specified.
|
|
|
|
Usage example:
|
|
|
|
Examples:
|
|
x11=no (disables X11 support)
|
|
x11=yes (will search for the package installation dir)
|
|
x11=/usr/local/X11 (will check this path for existance)
|
|
|
|
To replace autoconf's --with-xxx=yyy
|
|
|
|
opts = Options()
|
|
|
|
opts = Options()
|
|
opts.Add(PathOption('qtdir',
|
|
'where the root of Qt is installed',
|
|
qtdir))
|
|
opts.Add(PathOption('qt_includes',
|
|
'where the Qt includes are installed',
|
|
'$qtdir/includes'))
|
|
opts.Add(PathOption('qt_libraries',
|
|
'where the Qt library is installed',
|
|
'$qtdir/lib'))
