- # On Ubuntu 14.04, the libboost-python1.54-dev package comes with one library
- # for each Python version:
- # libboost_python-py27.so
- # libboost_python-py33.so
- # libboost_python-py34.so
- #
- # Boost upstream however installs Boost.Python3 libboost_python3.so, which is
- # what FindBoost.cmake is looking for. It looks for a library named
- # "libboost_${component}.so".
- #
- # On Gentoo instead, the >=dev-libs/boost-1.54 package provides boost library
- # with a name like:
- # libboost_python-2.7.so
- # libboost_python-3.3.so
- # libboost_python-3.4.so
- # depending on what python's targets you selected during install
- #
- # On Fedora >= 30 instead, the boost-python3-devel provides boost library with a
- # name like:
- # libboost_python37.so
- # depending on what python's targets you selected during install
- #
- # find_boost_python3() tries to find the package with different component
- # names. By default it tries "python3", "python-py$suffix" and
- # "python-$dotsuffix", where suffix is based on the `python_version` argument.
- # One can supply a custom component name by setting the
- # `CALAMARES_BOOST_PYTHON3_COMPONENT` variable at CMake time.
