Solution: Add a trace function.
Requires to move the CI build helper code/check/init/... at the end of
helper file.
This new function is available for (and also used by) build.sh.
Output is like:
LIBZMQ (x86_64) - Blah ...
To be reported to CZMQ/ZYRE via ZProject.

# The following is a helper script for setting up android builds for
|
|
# "native" libraries maintained with an autotools build system.
|
|
# It merely helps to create the proper cross-compile environment.
|
|
# It makes no attempt to wrap the library or make it accessible to Java code;
|
|
# the intention is to make the bare library available to other "native" code.
|
|
#

# To get the latest version of this script, please download from:

|
|

|
|
# You are free to modify this script, but if you add improvements,
|
|
# please consider submitting a pull request to the aforementioned upstream
|
|
# repository for the benefit of other users.
