## This is the minimal template for CMakeList.txt which could be used
|
|
|
|
|
## to build libmdbx from the "amalgamated form" of libmdbx's source code.
|
|
|
|
|
##
|
|
|
|
|
## The amalgamated form is intended to embedding libmdbx in other projects
|
|
|
|
|
## in cases when using as git-submodule is not acceptable or inconveniently.
|
|
|
|
|
##
|
|
|
|
|
## The amalgamated form could be generated from full git repository
|
|
|
|
|
## on Linux just by `make dist`.

## libmdbx = { Revised and extended descendant of Symas LMDB. }
|
|
|
|
|
## Please see README.md at https://github.com/leo-yuriev/libmdbx
|
|
|
|
|
##
|
|
|
|
|
## Libmdbx is superior to LMDB in terms of features and reliability,
|
|
|
|
|
## not inferior in performance. libmdbx works on Linux, FreeBSD, MacOS X
|
|
|
|
|
## and other systems compliant with POSIX.1-2008, but also support Windows
|
|
|
|
|
## as a complementary platform.
|
|
|
|
|
##
|
|
|
|
|
## The next version is under active non-public development and will be
|
|
|
|
|
## released as MithrilDB and libmithrildb for libraries & packages.
|
|
|
|
|
## Admittedly mythical Mithril is resembling silver but being stronger and
|
|
|
|
|
## lighter than steel. Therefore MithrilDB is rightly relevant name.
|
|
|
|
|
##
|
|
|
|
|
## MithrilDB will be radically different from libmdbx by the new database
|
|
|
|
|
## format and API based on C++17, as well as the Apache 2.0 License.
|
|
|
|
|
## The goal of this revolution is to provide a clearer and robust API,
|
|
|
|
|
## add more features and new valuable properties of database.
|
|
|
|
|
##
|
|
|
|
|
## The Future will (be) Positive. Всё будет хорошо.
