CMake Build Failure ["debug" argument must be followed by a library]

[acxz]

Description

gtsam does not build, in fact cmake fails.

Steps to reproduce

1. Clone gtsam
2. cd gtsam && mkdir build && cd build
3. cmake ..

Expected behavior

cmake command should not error out and finish successfully.

Environment

gtsam: develop branch
cmake: 3.15.4
boost: 1.71.0
OS: ArchLinux

Additional information

After some prelim debugging, it seems as tho in the latest cmake version (or the latest boost version), you cannot have empty fields after library identifies such as debug. Since I am not building gtsam in debug mode, the following variables are empty for me and as such when calling ${WRAP_BOOST_LIBRARIES} further in the CMakeLists.txt, the above error triggers. This happens not just in the wrap/CMakeLists.txt but also in other locations where debug is specified in the variable name, but no debug libraries are included. Another case is with ${GTSAM_BOOST_LIBRARIES} here with the relevant definition happening here.

I think PR #135 should fix this one too.
Please, give a try to that PR and confirm it to us.

[acxz]

Just checked the PR and cmake works fine! Hopefully this PR can get merged ASAP and a new release made, so ArchLinux users can have a working gtsam package.

EDIT: I'll go ahead and close this issue once the PR is merged.

I merged #135 and will close this issue for you :-) Thanks for helping to make GTSAM better!

[acxz]

Thanks for the super quick response, really means a lot!

Hi, I was using tag 4.0.0 but this problem is still there.
Error message like ...
CMake Warning (dev) at wrap/CMakeLists.txt:29 (target_link_libraries):
Link library type specifier "optimized" is followed by specifier "debug"
instead of a library name. The first specifier will be ignored.
This warning is for project developers. Use -Wno-dev to suppress it.

CMake Error at wrap/CMakeLists.txt:29 (target_link_libraries):
The "debug" argument must be followed by a library.

Could you tell me which tag has fixed your error? @acxz
