Using a variable in makefile which takes values from an external file.

Hello

I am currently having a Makefile which takes a list of packages and stores it in a variable

Code:

packages=\
package1 \
package2 \
package3 \

I want to populate this variable by reading from an external file, say in this case package.log which has a list of variables and looks like this.

Code:

package1
package2
package3

Is it possible to have such an arrangement?
If yes, please refer any document or link for this.

Regards,
Ashish

Code:

    contents := $(shell cat foo)

sets contents to the contents of the file foo, with a space (rather than a newline) separating each line.
