Hello everyone,
In a |CTest| process, I have to determine the |Boost_VERSION|.
To do so, I just add |FIND_PACKAGE(Boost)| to my configuration file.
I didn’t had any problems since a |cmake| update on Debian/SID to
cmake 3.5.0.
From now, I have:
|-- Looking for boost CMake Error at
/usr/share/cmake-3.5/Modules/FindBoost.cmake:896 (add_library):
Unknown CMake command "add_library". Call Stack (most recent call
first): /home/vhuber/feelpp/cmake/dashboard/testsuite.cmake:328
(FIND_PACKAGE)|
If I run a standard |cmake| process with a |FIND_PACKAGE(Boost)|
everything goes well.
I do not clearly understand what is going on.
add_library() is used by an increasing number of find modules to define
IMPORTED targets.
IMPORTED targets are the preferred and most convenient way to use
libraries located by find modules.
Since add_library() is only meaningful in build system definitions it is
not available to ctest.
I do not have theses problems with cmake 3.4.3
What can I do to solve that problem ?
You haven't mentioned why you need to determine the Boost version in
your ctest script but if you do still require it I would implement
custom logic (you could base it on the existing logic in FindBoost.cmake).
Using library find modules from any context other than cmake project
files is ill defined even before the changes that introduced imported
targets.
The boost find module specifically uses compiler and platform
information that is not available in ctest scripts (e.g. boost library
file names can be mangled differently depending on which
compilers/versions are used and can be located differently depending on
bitness).
