c++ - Share variables between makefiles -

i have directory construction want 1 main makefile in main folder, , makefile in both test , src folder.

in main makefile, have directives both test / phone call individual folder makefiles. i'm trying declare variables in main makefile , have them accessible other folders.

for instance in main makefile

packages = jansson mysql .... all: here test: cd test create test

and in test/makefile want able access previous packages variable , add together makefile's individual dependencies onto it.

in test/makefile

packages += googletest googlemock test here

could help me solve problem?

thanks

you can create file, instance makefile.variable shared variables defined , include file using

include $(pathtosharedmakefile)/makefile.variable

look @ include manual more information

c++ compilation makefile
