[Boost-build] Question about SHELL command

From: Chris Stankevitz (chrisstankevitz_at_[hidden])

Boost.Jam  Version 3.1.13. OS=LINUX.

Question:
How do I store the result of a shell command to a
variable?

Thank you,

Chris

PS: The following does not work:

# Jamfile
WXFLAGS = SHELL("wx-config --cppflags") ;
echo $(WXFLAGS) ;

$ jam
SHELL(wx-config --cppflags)
...found 7 targets...
$ 

I expected to see something that looked like this:
$ wx-config --cppflags
-I/usr/lib/wx/include/gtk2-unicode-release-2.6
-I/usr/include/wx-2.6 -DGTK_NO_CHECK_CASTS -D__WXGTK__
-D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -DNO_GCC_PRAGMA
$
