// TODO: Detect circular dependencies
// TODO: Prevent infinite recursion in source file searching when there are symlinks.
// Either do not follow the symlinks or use a hash map with every searched directory
// to only go inside a directory once
// TODO: Places that use PATH_MAX should be modified. A path CAN be longer than PATH_MAX... (does this include replacing tinydir.h?)
// TODO: Remove install.sh when sibs supports installation of packages (so it can install itself)
// TODO: Move package tests, include_dirs and ignore_dirs under config in project.conf.
// Package object should only contain metadata for the package, which is used for finding dependencies
// and when building a list of installed packages / available packages.
// TODO: Allow different platforms to have different dependencies.
// This can be done by specifying dependencies under [dependencies.platform] instead of [dependencies],
// for example for win32: [dependencies.win32]
// TODO: When `install` command is added, the target executable and shared library dependencies should be put into
// an archive to make the executable distributable (especially on windows). A GUI installer could then extract the archive.
// TODO: Add optional dependencies [optional_dependencies]. Optional dependencies should also support platform specific dependencies [dependencies.cmake].
// Might need to make it possible to define variables if a dependency exists (or doesn't exist) because the code might have
// preprocessor like: USE_LIBSODIUM or NO_LIBSODIUM.
// TODO: Set c++ standard to c++11 and c standard to c98 - for consistency across different compilers and compiler version.
// It should be possible to override language version in project.conf
// TODO: If file extension is common c extension (.c, ...) then remove cast checking (for example using malloc without casting result to result type)
// TODO: When building a sibs project, add a hardlink in ~/.sibs/lib to it. This allows us to have dependency to a project that we can modify
// without having to commit & push to remote
// TODO: Check compiler flags generated by cmake and visual studio in debug and release mode and use the same ones when building sibs project.
// There are certain compiler flags we do not currently have, for example _ITERATOR_DEBUG_LEVEL in debug mode which enables runtime checks.
// You should be able to specify runtime checks as an option to `sibs build` and project specific config in .conf file.
// Also add stack protection option. If it's enabled, shouldn't sibs prefer to compile dependencies from source?
// and should this force static compilation so dependencies can also be built with protection and if dependencies dont exist
// as static library/source, then fail build?
// TODO: Add support for common package managers (in distros). If package with the dependency version exists in package manager, install and use it instead
// TODO: Make dependency/project names case insensitive. This means we can't use pkgconfig
