Hello,
Here's my bug report, I'm building my software out of the source tree, this is
called parallel build (very nice feature).
The way to reproduce the issue is very simple, set myprog_CXXFLAGS = -DANY and
VPATH=@MYDIR@ and the corresponding Makefile won't find my source file. Replace
myprog_CXXFLAGS by AM_CXXFLAGS and it works well.
Autoconf 2.69, automake 1.13.4

Makefile.am :

myprog_SOURCES = Main.cpp
myprog_CXXFLAGS = -DANY

VPATH=@MYPROG_PATH@
I tried to set myprog_CXXFLAGS anywhere else in the file, but the issue is
still the same. Same behavior applies to myprog_LDADD, myprog_CFLAGS and so on.
Hope my bug report is detailed enough.
Julien
