Identifying & restricting NCS version in CMakeLists.txt

[Jason Wright]

Hi,

My project is set up as out-of-tree using NCS v2.0.0. I would like to restrict the NCS version such that it will throw a compile-time error if a non-matching version of NCS is used to build.

Is there a convenient way to do this with cmake?

Hi

I looked through our nRF Connect SDK, but found no variables for the version number.

So I think the easiest way would be to call git from CMakeLists.txt:

set(NRF $ENV{ZEPHYR_BASE}/../nrf/)
execute_process(COMMAND git describe --tags WORKING_DIRECTORY "${NRF}")

Just found a better way:

Version is in nrf/VERSION:

set(NRF $ENV{ZEPHYR_BASE}/../nrf/)
file(READ "${NRF}/VERSION" version)
message("${version}")
