# We unconditionally build implementations for C++ and Python. We plan to build
# and install the C library once we have clarity on where to install its
# headers, https://github.com/cucumber/gherkin/pull/346. For now, nothing is
# expected to require the C library in the short term, and we do not want to
# have to move the headers if upstream ends up requesting changes to the PR.

# Implementations for various other languages are present in the source. Some,
# like Dart, belong to ecosystems that are not packaged. Others, like Perl,
# could probably be enabled if motivation existed. Still others, like Go or
# Ruby, might be (if they are needed) better as separate source packages.

# For both C and C++:
BuildRequires:  cmake
# Faster than the "UNIX Makefiles" cmake backend, with no disadvantages
BuildRequires:  ninja-build
# C++ library has "LANGUAGES C CXX" in CMake, so it still needs a C compiler
BuildRequires:  gcc

# For C++ only:
BuildRequires:  gcc-c++
BuildRequires:  cmake(nlohmann_json)
BuildRequires:  cmake(cucumber_messages)
