I use VPATH to tell GNU make to look in other directories.

For example, one of my Makefile.am's has this definition:

VPATH = @srcdir@ : \
@top_srcdir@/drv/Geom : @top_srcdir@/src/Geom: \
@top_srcdir@/drv/TColGeom : @top_srcdir@/src/TColGeom: \
@top_srcdir@/drv/GeomAdaptor : @top_srcdir@/src/GeomAdaptor: \
@top_srcdir@/drv/AdvApprox : @top_srcdir@/src/AdvApprox: \
@top_srcdir@/drv/GeomLProp : @top_srcdir@/src/GeomLProp: \
@top_srcdir@/drv/Adaptor3d : @top_srcdir@/src/Adaptor3d: \
@top_srcdir@/src/TKG2d

You need to have @srcdir@ in there, the other directories
are where any other files make needs to know about, such as source.
On some platforms the native 'make' does not support VPATH,
but it is simple enough to install GNU make to fix that.
