For an example, pattern file Makefile.pat is as

1
2
3
4

...
CFLAGS=-g -Iinclude @original_includes@
LDFLAGS=-pthread -lm
...

from which the catch_inc.sh script can generate Makefile like

1
2
3
4

...
CFLAGS=-g -Iinclude -Ioriginal_inc/subdir/in/other/project/inc1 -Ioriginal_inc/subdir/in/other/project/common/inc2
LDFLAGS=-pthread -lm
...
