Hi CMake people,
I am trying to configure CMake to retrieve boost, and then run boosts bcp tool
to extract a subset of boost (math/special_functions) that I need for my
project. I had it working before, but now I'm not sure what went wrong.
Right now when I build, CMake is able to retrieve the boost zip archive from
their website, extract it, and run bcp to extract the subset, but now when I
build my project that depends on the imported boost library it is looking for
.obj files.
Since boost is header only, it doesn't need to be built, so should CMake be
looking for library files?
This is the contents of CMakeLists-BOOST.txt that the main CMakeLists.txt
calls. The boost-bcp.py script is able to extract the subset of header files
that I need, so the problem shouldn't be in there.
Any help is appreciated, thank you
