CMake Error at lib/CMakeLists.txt:67 -- (Boost) target not found?

[kmihaylov]

Excuse me for flooding with issue posts. I'm using @antoniprzybylik's #4
On my Ubuntu 18.04 machine I installed GR 3.8.2.0 (Python 3.6.9) from PPA repo.
However test-multi_rtl doesn't find Boost targets:

The configure script successfully finds the Boost libraries. Is it kind of dependency tree that somehow misses the correct path?

Do you have libboost-dev or libboost-thread-dev package installed on your system?

In Ubuntu/Debian boost's header files are in multiple sub-packages and it's usually easier to have them all by installing libboost-dev instead of the various dedicated sub-packages https://packages.ubuntu.com/bionic/libboost1.65-dev

[kmihaylov]

Yes, I have

Also I found the files here: /usr/lib/x86_64-linux-gnu

Is it possible that cmake searches another path?
What's interesting is that the output of cmake .. actually finds Boost:

-- Boost version: 1.65.1
-- Found the following Boost libraries:
--   filesystem
--   system

It is the lib/CMakeLists.txt:67 that states the missing library...?

[velichkov]

Open top-level CMakeLists.txt and add thread, program_options and regex on line 61.

Most probably you will need to add program_options and regex as well.

Thank you @velichkov . Your patch did the job! Saved the day one more time.
Thanks to @antoniprzybylik also for his port to GR 3.8 and quick reaction to the discussed bugs.
